Analysis of Geo-graphical Routing in Wireless Adhoc Networks

ABSTRACT Wireless mobile adhoc platforms such as manned or unmanned vehicles and peer-assisted key communication is an enabler for a vast number of routing protocol that directs the packets in the network. Mobile networks uses routing packets in fully connected mobile ad hoc networks (MANETs) has been studied to a great extent, but the assumption on full connectivity is generally not valid in a real system. Geo-graphical routing protocol must handle intermittent connectivity and the absence of end-to-end connections called location-aware routing for delay-tolerant networks (LAROD), enhanced with a location service, location dissemination service (LoDiS), intermittently connected with MANET . this approach overhead, LAROD uses a beaconless strategy combined with a position-based resolution of bids when forwarding packets. LoDiS maintains a local dataset of node locations, which is updated using broadcast review combined with routing overhearing. Our analysis design in a real time application with holistic choices in routing, location management, and the mobility model and identifies the choice of maintaining a local database of node locations is both essential and feasible, compares with a leading delay-tolerant routing algorithm (spray and wait) and is shown to have a competitive edge, both in terms of delivery ratio and overhead.
