Geographical Routing in MANET using Flexible Combination of Push and Pull Algorithm

E. Rathidevi | N. Senthil Kumaran

Abstract: Combining mobile platforms such as manned or unmanned vehicles and peer assisted wireless communication is an enabler for a vast number of applications. A key enabler for the applications is the routing protocol FGRP that directs the packets in the network. The FGRP protocol has been implemented using GLOMOSIM simulator. 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. This means that a practical routing protocol must handle intermittent connectivity and the absence of end-to-end connections. Routing overhead increase as data bits added to user-transmitted data, for carrying routing information and error correcting and operational instructions. Routing overhead because of location information collection and retrieving information using geographic routing in MANET. Developing a new framework for quantifying routing overhead in MANETs employing geographic routing, examining how the routing overhead (measured in the unit of bits meters per unit time) proposed required to disseminate and acquire location information of the nodes, scales with the number of nodes. For Spray and Wait this involved a new packet level implementation in GLOMOSIM as opposed to the original connection level custom simulator. Assume that nodes can deliver their location information at timeslot t 2 f1; 2;. . . g ¼: IN to any other nodes within the same timeslot, assuming that nodes know where to access it, they can retrieve the location information of other nodes during the same timeslot.
