Topology control in a wireless sensor network is useful for ensuring that the network remains connected in the presence of nodes that exhaust their energy or become altogether dysfunctional (for whatever reasons). It also ensures that all the link that can be established are energy-efficient links and the nodes utilize their energy fairly. In this paper, we propose a fair and energy efficient topology...
Wireless ad hoc networks are self-configurable distributed systems. One of the major problems in traditional wireless ad hoc networks is interference. The interference could be reduced using smart directional antennas. In this study, multibeam smart antennas have been used. When using this type of antenna, two nodes can communicate when both the sending and receiving beams are pointing towards each...
We present a localized algorithm (LTCA) for topology control in wireless sensor networks which has certain desirable properties. First, the algorithm is very simple, strictly local (requires 1-hop information of neighbors) and fast, requiring each node to communicate with its neighbors exactly twice. Second, LTCA does not assume the underlying graph to be a unit disk graph, and in fact works on general...
