Adaptive Path Energy Conserving Routing in MANETs
Hasnaa Moustafa and Houda Labiod

In this paper, we present a full performance analysis of an energy conserving routing protocol in mobile ad hoc networks, named energy conserving dynamic source routing (EC-DSR) protocol. Our performance analysis is carried out through investigating the impact of different mobility models on the protocol’s performance. EC-DSR attempts to minimize both routing and storage overhead, providing robustness towards host mobility and adaptability to wireless channel fluctuations. The innovation in our scheme is to handle nodes’ energy consumption increasing the durability of the power resource, and therefore the lifetime of the nodes and the whole MANET. Further, it handles network state related constraints such as links’ availability and paths’ quality. Indeed, grouped motion behavior is very likely to occur in an ad hoc network, as in disaster recovery or military deployment where collaborative behavior among some nodes is quite normal. To this end, we use two different group mobility models in our performance analysis, named Pursue and Reference Point Group Mobility (RPGM) models. We analyze and evaluate the impact of these two models on EC-DSR performance, comparing it to that of Random Way Point (RWP) model. We carry out our performance evaluation under realistic conditions, including realistic movements of mobile nodes, in the form of different mobility models. Our goal is to illustrate how the performance criteria of our protocol can be highly affected by the mobility behavior of nodes.
