- Abstract
- Wireless ad-hoc and sensor networks are energy constrained because nodes are strongly dependent on their batteries. Topology Control (TC) is one of the most important technique used to reduce energy consumption. This technique coordinates the decisions of network nodes about their transmission power to save energy, prolong network lifetime, and mitigate MAC-level medium contention, while maintaining network connectivity. TC protocols share many commonalities and basic components such as neighbourhood sensing and transmission power adjustment mechanism at the physical layer. Based on this observation and in order to ease the implementation and the study in systematic way of proposed TC protocols, we propose a new framework based on NS-2 simulator. The framework is modular and generic since it implements a set of basic components used by TC protocols. We illustrate, by an example, how the framework facilitates the implementation and performance evaluation of TC protocols.
