단말의 에너지 효율을 고려한 무선 Ad-hoc 라우팅 프로토콜

Abstract

In this paper we propose a new routing protocol, which takes residue energy of nodes into account in order to prevent node failures resulting from energy shortage. Our routing protocol examines the smallest value of node residue energy (Em) from each of all possible routing paths and selects the path which has the largest value of Em. We prove, through simulation, that our routing protocol extends the lifetime of nodes which have limited amount of energy, reducing chances of path replacement. It is also shown that our proposed protocol helps alleviate network performance degradation.
