Location Aided Routing Protocol for Mobile Ad-Hoc Network - Wave Zone Approach
The Mobile Ad-hoc Networks can be differentiated from other network by its many unique characters. This supports random movement of nodes, dynamic synchronization mechanism and infrastructure free connection between mobile nodes. Even though it has many unique features and portable nature, MANET poses a major challenge that is implementation of a routing protocol design for it. This is even more complicated when the protocol achieves good performance in terms of energy, resource usage and packet delivery. This can be possible with effective development of routing protocol for MANET. Hence the objective of this paper is to produce energy efficient routing protocol without compromising on the quality of service (QOS). To achieve this, a Wave Zone based Location Aided Routing (WZLAR) Protocol is proposed, that integrates the zone routing mechanism with the location aided node selection schemes. The WZLAR also aims to provide high performance outcome in terms of large mobile nodes and zone size. The simulation results of WZLAR show an increase in energy efficiency than existing approaches. The WZLAR protocol proves to be efficient by producing better packet delivery ratio for low and high-density networks. The NS-2 simulation results also show that the WZLAR produces a significant saving in energy consumption, and a substantial increase in packet delivery ratio compared to existing protocol.
