Abstract: The aim of topology control in MANET is to reduce the transmission power at each node level to maintain the network topology and reduce the energy consumption as well. Controlling the transmission radii of nodes decreases the radio interference which in turn increases the spatial reuse of channel. The location of neighbour and direction are obtained by Global Positioning System (GPS) and angle of arrival. To reduce the hardware cost, only group of nodes are loaded with GPS device while remaining nodes in the network get the location information. Several protocols based on location information have been proposed to control the topology of the network. We have proposed a modified approach to the Location Based Topology Control which takes into account of interference and delay constraints. Extensive simulation is carried using QualNet simulator to compare our proposed scheme with the existing protocol. The simulation results confirm that the proposed scheme out performs in terms of throughput.
