Evaluation of the Energy Consumption in MANET

摘要

In mobile ad hoc wireless networks, energy consumption is an important issue as most mobile nodes operate on limited battery resources. Existing models for evaluating the energy consumption in a mobile ad hoc network have shown that the various components of energy related costs include transmission power as well as the reception power. In this paper, we extend the model for calculating the energy spent at a node due to a flow in the network. We include the transmission and reception costs if the node belongs to a flow, and reception costs if it is near a flow. This model gives the energy costs of nodes in ideal conditions where interferences are absent. It is then extended to evaluate the interference effect on energy consumption in more realistic conditions. The collisions due to concurrent flows are also measured. We then show how the extra energy spent due to collisions can be calculated by predicting the collisions in the nodes of the network. This prediction is shown to be capable of accurate calculation of the extra energy consumption.
