Fountain codes are widely employed to improve reliability and efficiency in wireless communication systems due their simple coding mechanisms. In this letter, we propose an opportunistic decoding recoding mechanism with coordinative routing algorithm for fountain the expected transmission counts (ETX) performance reduce computational complexity of at each relay multi-hop sensor networks. The fu...

In wireless mesh networks, the routing of packets from source to destination is crucial and challenging task. The wireless mesh networks find applications in disaster management, video on demand, intelligent, health care systems, etc. Various routing protocols exist in literature to improve the efficiency of the wireless mesh networks calculated in terms of reliability, cost, throughput, error ...

This paper investigates combining opportunistic routing techniques with multipath routing for achieving reliability and timeliness in fast-changing network conditions. We present two approaches, WIMOP and DOMR, based on source routing and distributed routing, respectively. Instead of using broadcast packets as in most opportunistic routing work, we use unicast with promiscuous listening so that...

Designing a multi-constrained QoS (Quality of service) communication protocol for mission-critical applications that seeks a path connecting source node and destination node that satisfies multiple QoS constrains such as energy cost, delay, and reliability imposes a great challenge in Wireless Sensor Networks (WSNs). In such challenging dynamic environment, traditional routing and layered infra...
