Abstract:


Background: Recent years have accentuated a remarkable rise in the popularity in the field of mobile computing owing to the size reduction of the computing devices and it is also contributed by the exceptional increase in the processing power availability of mobile laptops rendering various computer applications to reach the ever-rising population segment. This increase in the number of users poses more challenges in the field of networking. The various most specific constraints that exist in the wireless mobile infrastructure-less networking environment having compact batteries as the storehouses of power are power consumption and energy enrichment.

Methods: The application of Route Aggregation in MANET thrives to improve the energy efficiency in MANET by aggregation of routes and therefore achieving a significant saving in the scarce resources. The methodology takes into account a Hybrid protocol, Zone Routing Protocol with aggregated routes and selection of a Head in the aggregation Zone. The Head now takes the responsibility of the routes and the data delivery along the routes within the aggregation Zone. The formation of such Heads and Aggregation Zones reduces the energy dissipated at each node while ROUTE DISCOVERY phase as the routes are readily available at the Head. The procedure thus proves effective in saving energy as well as bandwidth. Aggregation has so far has been able to curb the problems caused in order to improve the scalability of the network. This paper studies and analyses various aggregation techniques applied in Mobile Ad-hoc Network (MANET) points out the improvements in various QOS parameters resulted due to the application of aggregation on routes, data and address in the field of MANETs.

Results: The results of graphs validate the proposed approach and specify improvement of energy consumption which is the need of hour. The results also justify the novel approach by varying various parameters like number of nodes, pause time and simulation time showing improvement in average energy consumption for the novel RA-ZRP approach.

Conclusion: The random cluster head selection based routing approach also referred as route aggregation approach is used for energy enhancement which is depicted in section above. NS2 simulated results presented in this paper validate the proposed approach. The ZRP-RA based random cluster selection energy enrichment approach helps in reducing the various control and routing overheads involved in the functioning of ZRP. It also reduces the number of route requests to be sent and thus superfluous route requests can be avoided and thus saving in bandwidth is achieved also the reduction in the routing and control overhead reduces the probability of collisions and thus the data is effectively forwarded to the destination. This also helps improve latency as the queuing up of data packets is lessened owing to the less overhead.
