PAMP: Power-Aware Multi-Path Routing Protocol for a Wireless Ad Hoc Network

In a wireless ad hoc network, the limited energy of the nodes is one of major challenges. Many research works are proposed to solve this issue from various aspects. Our work focuses on how to utilize the limited energy of the nodes in data delivery. By combining the concept of multi-path routing and energy reservation, the proposed scheme, PAMP ensures to make a way to delivery packets even though the nodes can not fully satisfy the energy request of the source. PAMP is designed as an extension of the existing AODV by modifying RREQ and RREP management mechanism to handle energy reservation and multiple paths. When compared with other energy-aware routing schemes and AODV, the proposed scheme gives significantly higher data reliability and network lifetime.
