In this chapter represented the cooperative communication and explain the different between the Multi-Input Multi-Output (MIMO) and cooperative communication .
Also this chapter the advantages and disadvantages of network coding are introduced. Then linear network coding (encoding and decoding) is provided. Finally, the applications of network coding are explained.
Also this chapter error detection and correction that data link layer responsible of them by using Convolutional Coding(CC).
3.2Cooperative communication :
Wireless is one of the most rapidly developing technologies in our time, with dazzling new products and services emerging on an almost daily basis. These developments present enormous challenges for communications engineers, as the demand for increased wireless communication distance , interference reduction and improvement throughput in wireless network.[1]
This the above challenges can be solve by using MIMO (multiple-input multiple-output)generally requires more than one antenna at the transmitter and at the receiver. However , many wireless and wireless sensor network devices are limited by size or hardware complexity to one antenna. Recently, anew class of methods have the same advantage MIMO system called cooperative communication has been proposed that enables single antenna mobiles in a multi-user environment to share their antennas and generate a virtual MIMO transmitter that allows them to achieve

404 Words | 2 PagesWhen one receives a signal, it must wait for the transmitter to stop transmitting, before replying. In these half-duplex systems, if more than one emits a transmission at the same time, a collision will occurs and messages will be lost. The messages sent by nodes are corrupted. The receiving nodes receive random data.

452 Words | 2 PagesSpecialist Dental Services (SDS) has an existing Token ring infrastructural that uses IEEE 802.5 standard, meaning that it is a local area network in which all computers are liked in ring or start topology. A token (special bit pattern that travels around the circle, computer catches token to send a message, after attaching massage token is then continues traveling around the network) design is used to prevent collision of date between messages that were send at the same time. In the token ring infrastructure data rate transfer is 4 to 16 Mbps, with shielded and unshielded twisted-pair cabling of 1,2,3 IBM types to wire a token network. An Ethernet is different, since whenever any computer needs to send data, it does not need a token to send a message, any computer can send data at any time.

385 Words | 2 PagesThe aim of SAR algorithm is to reduce average weighted QoS metric throughout network lifetime. Another wireless sensor network QoS routing protocol that ensures soft real-time end- to-end guarantees is SPEED that ensures avoidance of congestion during network congestion. Diff-MAC is a Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) based QoS-aware MAC protocol with differentiated services and hybrid prioritization. Diff-MAC aims at increasing the utilization of the channel with effective service differentiation mechanisms while providing fair and fast delivery of the data.

984 Words | 4 PagesIn our simulations, there are one MeNB and one SeNB, and the distance between MeNB and SeNB is 1 km. All UEs are assumed to have dual connectivity capability, and their initial locations are randomly assigned. A UE can connect to the SeNB if the detected signal strength on that SeNB is larger than $-75$ dBm. Each UE is configured to have one bearer, and the traffic type of the bearer is constant bit rate (CBR). For a UE, it may receive data from MeNB, SeNB or both of MeNB and SeNB depending on its location or the decisions of our traffic scheduler.

Fault tolerance: Routing protocols should have fault tolerance. WSNs nodes are susceptible to failure, therefore, a protocol should make full usage of the network information which is simply retrieve by a node for calculating routes, so as to assure that the routing failure can be recovered as soon as possible; multi-path transmission can also enhance the data transmission reliability. 4.

604 Words | 3 PagesOne to one communication: One to one communication is a conversation between two people; which does not include a third person. This type of conversation has a start; which means the conversation has to start off with a greeting, one to one communication al so includes a middle section, which is when you and the person discuss the topic or of what your both going to be speaking about. This particular type of communication also needs an ending, for example when the conversation is coming to an end you can end it by saying “good bye” or “see you later”. Group communication: group communication is when everyone is involved in the conversation/ discussion, it works out best id there is someone in charge such as a team leader , who makes sure everyone

Whether you are a family home, a mom and pop shop, a data center or large corporation- there is a network for your needs. A network is a system of operating machines that allows a user to access an interface suitable for creating and saving documents, access webpages and video/audio content, run administrative programs to serve clients based on whatever business model or service provider you are. First let’s discuss a peer to peer network.

173 Words | 1 PagesData Communication protocols are formal descriptions of data formats and rules in which the more than one system exchanges data /information. The protocols cover various issues such as authentication, error detection and correction. Popular network communications protocols used are the TCP/IP and User Datagram Protocol (UDP), while TCP is connection oriented once a connection is established, UDP connectionless Internet protocol. The model for information exchange includes the data source which generates the data to be transmitted, Transmitter which converts the data into transmittable signals, Transmission system which carries the data, Receiver which converts received signals into data and Destination which takes incoming data. TCP/IP uses
