Abstract

A Wireless Sensor Network (WSN) essentially consists of data sensor nodes and video sensor nodes, which senses both sound and motion of events. Routing is the process of moving packets across a network from one node to another. It is usually performed by dedicated devices called routers. Single path routing protocol is used for route discovery and resource utilization. There are some drawbacks like reduced network throughput, network performance, increased traffic load and delay in data delivery. To overcome these problems, multipath routing is preferred. It is the method of using multiple paths in a network. A new system called Cost Based Multipath Routing (CBMR) for multimedia data is proposed based on multipath routing to improve the reliability of data transmission. The need for the proposed system is to provide multipath routing for multimedia data in an efficient manner where the best path is chosen based on the cost. . The proposed system incorporates Real-time Transmission Protocol (RTP) and Multiple Description Coding (MDC) for transmission of multimedia data. Using these techniques, the multimedia data is encoded into trace files at the sender side and the decoding of the trace files is performed at the receiver side. The generated trace files contain information about frames, pixels and headers. This system is applied between the source and sink in a wireless sensor network. The proposed protocol is simulated using Network Simulator2.
