M.P. Anuradha, Gopinath Ganapathy · Research Journal of Applied Sciences Engineering and Technology · 2013
Secure and optimistic routing is very important and significant task in Wireless Sensor Networks (WSN). In multi-hop communication, selection of routing path between the sensor nodes in the sensor field is essential and also important. Based on the coordination, time based, token based and network coding based techniques the data packets are forwarded from the source to the destination through the intermediate nodes in the network called Opportunistic Routing (OR). Compared with traditional routing, the OR uses the broadcast nature of transmission which greatly increases the wireless network throughput, reliability. In order to support higher node density in WSN, the selection of the most optimistic, flexible, dynamic and reliable OR mechanism and OR protocol are important. In this study the various OR mechanisms and OR protocol are identified and design issues like delivery ratio, packet transmission rate, communication pattern, reliability rate, throughput and fault tolerance are discussed and the comparative results are also tabulated.
