Performance Analysis of the Energy Fairness Cooperation Enforcement Mechanism (EFCEM) in Ad Hoc Networks

摘要

Mobile ad hoc networks must operate independent of fixed or centralized network management infrastructure, the communication between nodes rely on the node's cooperation, so nodes' selfish behavior to save the battery cost for their own communication cannot be neglect. However, general cooperation enforcement mechanisms do not consider node battery, so hotspot node issue may exist; even badly lead to network separation. This paper proposes an Energy Fairness Cooperation Enforcement Mechanism (EFCEM) in ad hoc networks. Theoretical analysis and numerical simulation results show that the EFCEM protocol, comparing with the traditional reputation mechanisms, can prolong networks existence time and improve network throughput, but at the cost of a little more packets delay.
