A New Location-Aware Hierarchical Routing Protocol forMANETs

摘要

In this paper, a new hierarchical routing protocol called Location-aware Grid-based Hierarchical Routing (LGHR) is proposed for mobile ad hoc networks where the network is partitioned into non-overlapping zones and each zone is then further divided into smaller grids. Although, the protocol is a location-aware routing protocol, the routing is performed similar to link state routing i.e., the neighbor node information is needed for creating routing tables and making forwarding decisions. LGHR attempts to overcome the weaknesses of some of the existing location-aware routing protocols for mobile ad hoc networks. The performance of LGHR is compared with tin existing location-aware routing protocol and the results show significant improvements of the proposed protocol over this protocol in terms of storage as well as communication overhead.
