An Energy-aware Multi-path And Multi-speed Routing Protocol In Ad Hoc Network

Ad Hoc network is a network that is flexible to build up, fast to deploy and has stronginvulnerability. It can be widely applied to both military and civil environments. However,Ad Hoc network routing techniques have become a key point of study for Ad Hoc networkbecause of its complex communication environment, multi-hop transmission, limitedenergy and computing capability.This paper first introduces Ad Hoc network routing techniques. Routing protocols areclassified and their performances are compared. Then we made a deep study in multi-pathrouting techniques and analysed several typical multi-path routing protocols. The problemsof providing QoS guarantee in Ad Hoc network and the present study situation areconcluded. The analysis shows that compared with single path routing protocols, multi-pathrouting protocols have many advantages such as balanced load, high transmissionreliability, low transmission delay and so on. Thus, multi-path routing protocols are morelikely to meet the requirements of QoS guarantee.This paper is a research based on the typical multi-path protocol AOMDV. We studiedits packet structures, route updating and maintaining mechanism and analysed itslimitations. According to these limitations, we proposed a energy aware multi-path andmulti-speed protocol EAMM based on packet resching probability and delay, each nodemakes routing decisions based on geographic progress towards the destination sink,required end-to-end reliability, delay to neighbor nodes and residual energy level. Wesimulated EAMM in NS2and made a comparison with AOMDV. The simulation resultsshow that EAMM has better performanees interms of packet resching probability,end-to-end delay and network lifetime.
