Analysis of energy and mobility model on opportunistic routing algorithms

Abstract

An Opportunistic Network is an extreme network where the communication mainly depends on the mobility of the participating nodes to address the intermittent connectivity. This opportunistic routing utilizes a store-carry-forward paradigm exploiting node mobility and local forwarding to transfer the messages. The mobile nodes are normally low-power portable wireless communication devices employing as wireless ad hoc network for multi-hop transmission. With the limited resource, the performance of the routing protocols can be degraded. Thus, it is vital to consider the energy consumption of the mobile node in this opportunistic environment, especially with different mobility patterns. This paper aims to study and analyze the energy usage on the node mobility. The results from the simulations show that MapBased mobility models consume more energy than random based mobility models while gaining higher delivery ratio. In the random based models, random direction consume more power than random waypoint and random walk respectively.
