Efficient Packet Transmission and Energy Optimization in Military Operation Scenarios of MANET

In recent years mobile ad hoc network has gained popularity with its wide range of applications. This has result into number of contributions toward the challenges of bring reliability in the network and enhance its packet transmission performance. Military and rescue operations are one of the highly sensitive applications of MANET. The objective of this research was to identify the networking gaps in MANET for military scenarios and enhance networks efficiency based on networks demand. This paper presents three different network situations and possible solutions. These approaches were analyzed with network simulations using NS2. The results of simulation have reflected positively for all three approaches. In the first case, the responsibility of cluster head was shared by dual cluster heads which reduces the energy consumption of cluster head by 12.4 %. The second case study identifies critical nodes and network was optimized to improve the life time of these critical nodes. Finally in the third case, study an enhanced architecture was analyzed which performs better at different mobility scenarios with an average of 1.41% higher packet delivery ratio.
