In current pure cellular networks, each and every mobile node updates it's location to the particular base station separately following certain algorithms, say timer based, mobility based or both. For the next generation wireless networks, which we can consider as a highly dense network, such location update algorithms prove to be very costly in the terms of overall location update traffic to the base station and average battery usage by each mobile node for location updates due to large number of mobile nodes for particular base station area.

Instead of using such one-to-one link for location updates, this report describes a new algorithm called 'Co-operative Location Updates' - in which many mobile nodes give their location details to one neighboring node and that node gives information to the base station. In this way, the traffic congestion to the base station due to location updates can be reduced drastically and also at the same time the average battery power used by the mobiles for location updates can be increased. Finally the work is proved by showing view graphs in the results section.
