A reactive Optimized Link State Routing protocol for Mobile ad hoc networks

Major constraints to be kept in mind while designing a routing protocol for ad hoc networks are battery power consumption, congestion control, time delay and the transmission range of the nodes. In this paper, we aim to develop an energy efficient and angular routing protocol, named Efficient Reactive and Angular - Optimized Link State Routing (ERA-OLSR). ERA-OLSR is an enhanced protocol designed over the well known Optimized Link State Routing (OLSR). ERA-OLSR is a reactive protocol which omits the use of routing table from OLSR and decides the next hop on the basis of angular concept. The proposed protocol has been compared with well established reactive protocols namely Ad-hoc On Demand Distance Vector Routing (AODV) and Dynamic Source Routing (DSR). The results achieved after implementing the proposed protocol establishes the fact that ERA-OLSR shows a better performance than both AODV and DSR in terms of End-to-end delay and Average Energy Consumption during the simulation.
