Abstract: Wireless technology has advanced tremendously over the past decade, introducing a wide array of devices with networking abilities. Adhoc networks are dynamically created and maintained by a group of wireless enabled devices (gargets) with out the assistance of pre-existing infrastructure like Base Station (BS) for communication purposes. In this study, we consider the issue of performance enhancement of wireless networks in terms of `overhead messages per node and power consumption`. Minimizing power consumption is an important challenge in mobile networks. Wireless network interface is often a device`s single largest consumer of power. To fulfill the above requirements, we have designed a topology management scheme for Adhoc wireless networks. In our topology management scheme, MARI(Mobile Agents with Routing intelligence) nodes are selected in such a way that, the MARI nodes have maximum power level among their one hop neighbors and all non-MARI nodes are with in the transmission range of MARI nodes. These MARI nodes have the routing intelligence i.e. they make all decisions relating to routing. The gateway nodes having sufficient power level are selected so that they can forward packets between MARI nodes. Gateway nodes do not have routing intelligence. These MARI and gateway nodes stay continuously awake to route the packets of other member nodes.
