Abstract: Planning, design and implementation of traffic infrastructure is a complex task especially when it is done for infrastructure located in urban areas because it depends on different factors and interests. This is why the solutions have to be evaluated by different type of criteria (traffic, economic, environmental and social). For this purpose during last decades multi-criteria methods came into use and numerous methods have been developed which are classified as multi-criteria analysis methods (e.g. PROMETHEE, TOPSIS, and AHP). In this paper the overview of how the multi-criteria analysis method AHP - Analytic Hierarchy Process is used as decision making tool in the process of transportation planning. AHP has been …show more content…
. “Optimal” refers to shortest time, shortest distance, or least total cost. A commuter while travelling from origin to destination always tries to find a path which will cost less time, minimum distance, good road condition. The analysis of transportation networks is one of many application areas in which the computation of shortest paths is one of the most fundamental problems. These have been the subject of extensive research for many years. The shortest path problem was one of the first network problems studied in terms of operations research. Fixed two specific nodes A and B in the network, the goal is to find a minimum cost way to go from A to B. Several algorithms for computing the shortest path between two nodes of a graph are …show more content…
A case study is carried out by using one day floating data in Wuhan, China. D. K. Parbat generated MPT (minimum path tree) using moore’s algorithm. The travel time study is conducted in Indore city, India using test car technique and MPT from each origin zone to all destination zone were obtained incorporating travel time and distance as factor separately. H.Ramzani, Y. Shafahi and S.E. Seyedabrishami proposed a method to solve shortest path problems in route choice process when each link travel time is fuzzy no. called as perceived travel time (PTT) which is subjective travel time perceived by a driver. They used FSPA (fuzzy shortest path algorithm) to find shortest path in an urban transportation network. Apeksha Khare proposed Adaptive Dynamic Route Planning (ADRP) algorithm in which vehicle continues to move on the shortest path or can opt for a minimum time taking route based on the requirement during travel from its source to destination. Lilli Qu and Yan chen (2008) set up Hybrid Multicriteria Decision Making (MCDM) on the basis of fuzzy analytic hierarchy process (AHP) and artificial neural network (ANN) theory for route selection of multimodal transportation network. Sadeghi-Niaraki et.al (2010) used multidimensional variables combined with multi-dimensional cost model (MCDM) to develop a road network cost function for route
• A cluster head is chosen when the network is first activated. • As a node drains its battery power totally, it becomes dead and is eliminated from the network. Calculating Node Weight: Distance traveled by a node Dv = sum [DISTv] In ‘n’ time units from i= t-n to i= t where t is the current time.
5. METHODOLOGY 5.1 Secure Multipath Routing Protocols in Wireless Sensor Networks Till date many routing protocols have been proposed for wireless sensor networks, but only few of them consider the problem of security [4] and most of them are developed without any security concern. So in this section we focus at selected multipath routing protocols in order to cope with the various attacks. For avoiding intruders attacks in HWSN various methods and algorithms are implemented out of that Professor Hamid Al-Hamadi and Professor Ing-Ray Chen:
However, significant overheads in terms of communication and storage are incurred due to the flooding or multi-hop forwarding [10, 11]. 3) Without the network infrastructure, steady connection between nodes is difficult to be guaranteed, especially in large scale VANETs. In other words, the scalability is difficult
j, the diagonal elements are made zero by replacing diagonal elements by zero. First, two matrices with the same k value are horizontally concatenated and then the matrices obtained after the horizontal concatenations are vertically concatenated to produce N1 - N2 adjacency matrix A. The numbers N1 and N2 represent the numbers of nodes of type 1 and type 2 respectively. The value of N1 is obtained by rounding the product of the network size N and the node proportion q1 of type 1 to the nearest integer. Then the remaining number of nodes N-N1 is the number N2 of nodes of
Task 1 1.1) Design a networked system to meet the given specification. Your design must satisfy the user requirements and be scalable. [3.1] The design of the network system should include: cost, Bandwidth, system growth, applications, communications, and scalability of the system and selection of components. Introduction - Designing the Network In this design I will be listing and discussing, through the different and necessary designing stages, the various elements involved in designing a network that meets the system requirements given by the client.
It has helped to describe the parameters with an emphasis on lifetime of network, reliability, and the dynamic and static of single and multi-hop networks
So, there are still some future investigation possible 8. Routing is a significant technique in wireless sensor networks in which experimenters are required to locate and
If an intermediate node receives another RREP after propagating the first RREP towards source it checks for destination sequence number of new RREP. The intermediate node updates routing information and propagates new RREP only, • If the Destination sequence number is greater, OR • If the new sequence number is same and hop count is small, OR Otherwise, it just skips the new RREP. This ensures that algorithm is loop-free and only the most effective route is used.
In the past, the traditional method of selecting a route involved finding the shortest path between two locations, gathering all relevant information pertaining to the route area (maps, photographs, field surveys,
Burke’s administrative duties require him to enact punishments under a roadmap system by use of infractions. Summ. J. Ex. F. 1-5. Although this roadmap sets up guidelines, the system, by its very nature, mandates the use of discretion.

Spreading of Diseases 1. Introduction Silk road is a name of a network of roads that was connecting Europe with East Asia. Name ''Silk road'' was invented in recent history, in XIX century. Describing trade routes, geographer Ferdinand fon Rihthofen used word "Seidenstrassen", but never really explained its real meaning.
Abstract – A main requirement in high performance networks is multicast communication, which involves transmitting information from a single source node to multiple destination nodes. A multicast assignment is a mapping from a set of network nodes called as source nodes, to a maximum set of network nodes called destination nodes with no overlapping allowed among the destination nodes of different source nodes A network is said to be nonblocking for multicast assignments, if for any legitimate multicast connection requests from a source node to a set of destination nodes, it is always possible to provide connection path through the network to satisfy the connection request without any disturbance to the existing connections. If the path selection
Edges can be either directed or undirected graph in a network. Adjacency list and adjacency matrix are used to represent edges in network formation. It helps to connect average shortest path length and high clustering. In social network graph can connect two people nodes and to check the account maintained by user in dataset. It matches with the user account and to generate a graph in gephi.
TRANSPORTATION Transportation means moving goods or people from one place to another place. With the increase of the population, transportation came in to consideration both in passenger and freight transportation. Transportation in urban cities has to meet
