Performance Analysis of Location-Aware Grid-Based Hierarchical Routing Protocol for Mobile Ad Hoc Networks

Abstract EN

In this paper, the performance analysis of a hierarchical routing protocol for mobile ad hoc networks (MANETs) called Location-aware Grid-based Hierarchical Routing (LGHR) is performed.

In LGHR, the network comprises nonoverlapping zones and each zone is further partitioned into smaller grids.

Although LGHR is a location-aware routing protocol, the routing mechanism is similar to the link-state routing.

The protocol overcomes some of the weaknesses of other existing location-based routing protocols such as Zone-based Hierarchical Link State (ZHLS) and GRID.

A detailed analysis of the LGHR routing protocol is performed and its performance is compared with both the above-mentioned protocols.

The comparison shows that LGHR works better than ZHLS in terms of storage overhead as well as communication overhead, whereas LGHR is more stable than GRID especially in scenarios where wireless nodes are moving with very high velocities.
