ABSTRACT

A mobile ad-hoc network is a mobile, multi-hop wireless network which is capable of autonomous operation whose primary role is to provide a reliable end to end communication between nodes in the network. However achieving reliable transmission in mobile wireless network is crucial due to change in the network topology caused by node mobility. Modern communication network is becoming increasing & diverse. This is the consequence of an increasing array of devices & services both wired & wireless. There are various protocols to facilitate communication in ad hoc network like DSR and TORA. However these approaches end up in the inefficient utilization of resources after link failure and congestion. This paper proposes an approach to get over this problem .We have added some static nodes which only keeps information related to the current working path and also helps in quick recovery in case of link failure.
