A Weighted Energy Aware Multipath Reliable Routing Mechanism for Hotline-Based WSNs

Alternative Abstract: Energy Efficiency and reliable source to sink communication is important in any mission critical WSN deployment. We present an efficient energy aware disjoint multipath routing protocol which utilizes a modified multipoint relay broadcasting technique to discover link disjoint multipaths. The protocol makes use of hotline topology in which the cluster heads or gateway nodes are interconnected with high speed reliable medium such as Ethernet. The protocol reduces the energy cost of network path discovery, makes the routing efficient by reducing the average hop count from source to destination and makes the routing robust by making use of partially link disjoint multipaths. We have compared our work to already well known protocol AOMDV and have also compared the performance of our work with WEAMR which is a similar protocol that utilizes the hotline based assisted routing. Our protocol efficiently utilizes multi point relay technique to minimize the cost of network multipath discovery and smartly switches between best possible path for data transmissions. The cost of multi paths is calculated based on latency, minimum energy node path value and end to end number of hops. Our simulation results show that the proposed scheme provides extremely efficient routing in terms of end to end delivery, lower packet loss ratio and improves overall network lifetime in terms of energy depletion as compared to WEAMR and AOMDV.
