By utilizing the multi-channel technology and small world properties, the average path length of a wireless network can be reduced drastically, leading to a significant improvement of network performance. By upgrading a fraction of nodes into the high-level nodes with multi interfaces and higher transmission powers, small world effect can be introduced owing to the short-cuts created by the high-level...
The diversity of the applications supported by wireless ad hoc and sensor networks explain the success of these networks. However, their energy constrained nature requires the use of energy efficient strategies to maximize network lifetime. We can classify these strategies in four categories: 1. energy efficient routing, 2. scheduling the nodes sleeping state, 3. topology control by tuning node transmission...
