Routing Protocol For Wireless Multimedia Sensor Network

Abstract

Wireless Multimedia sensor network(WMSN) is a network of interconnected devices by which we get multimedia content such as video streams, audio, still images data from the surrounding. Reliability, QoS, and high bandwidth demands are some additional challenges of WMSN as compare to wireless sensor Network. For achieving real- time requirements for multimedia delivery of data, new protocol need to be made which guarantee limited reaction time(End-to-End delay) as well as strive to minimize energy consumption in data processing and communication. The QoS requirements in WMSN are very not the same as traditional networks. In this report various QoS issues and functionality of all layers in WMSN are discussed. And it also explains the routing algorithms which support QoS required for the WMSN and comparison between them is done considering different parameters. The wireless sensor networks applications are supposed to solve the conflict of energy efficient communication and should achieve the desired qos like communication delay. To compensate this challenge we are proposing a new protocol PASPEED that is capable of achieving application specific delays at low energy cost and that can dynamically adapt routing decisions. The proposed protocol is characterized as stateless localized having minimum overhead. It forward the packet by choosing the most energy efficient choice from the neighborhood table according to the required speed maintaining the delivery speed also.
