Handover Count Based Location Aided Routing for Cluster Networks (HCBLR)

MANET (Mobile Ad hoc Network) being the centralized wireless network and due to the ease of deployment it has gained popularity very rapidly and has a wide acceptance in different areas. There is an increasing use of MANET technology in recent years where quick network establishment is required. Energy is the scarcest resource in MANET. Cluster based networks are used to reduce the energy consumption and also by means of controlled flooding using GPS (Global Positioning System). Significant amount of energy is consumed in GPS´s operation. Completely GPS free as well as GPS scarce positioning systems for wireless, mobile and ad hoc had been proposed by many authors in recent years. LAR (Location Aided Routing) scheme1 uses GPS to find the expected region, in order to provide controlled flooding. The amount of energy consumed and control overhead increases with the increase in the number of advertisement messages transmitted. In HCBLR (Handover Count Based Location Aided Routing for Cluster Networks) the expected region is calculated based on the handover count value of the mobile node, which forwards the flooding messages only to the cluster heads that are in the expected region. Thus there is reduced energy consumption when compared to other location based protocols.
