Position verification in wireless sensor networks (WSNs) is quite tricky in presence of attackers (malicious sensor nodes), who try to break the verification protocol by reporting their incorrect positions (locations) during the verification stage. In the literature of WSNs, most of the existing methods of position verification have used trusted verifiers, which are in fact vulnerable to attack...

The performance of wireless sensor networks (WSNs) is greatly influenced by their topology. WSNs with patterned topologies can efficiently save energy and achieve long networking lifetime. In this paper, we discuss different patterned topologies for constructing WSNs which can provide the required coverage area and the connectivity of all sensor nodes. We compare different performance measures ...

This paper deals with the joint planning and energy management operation of Wireless Mesh Networks. We claim that energy management should be incorporated at the planning stages to produce an effective energy-management operation. For this, we propose a mathematical framework that takes into account the trade-off of capital expenditures versus energy-related operational ones when designing the ...

In recent years, wireless LAN technologies have experienced unprecedented growth, and new services and problems have occurred. In this paper, we propose a position estimation technique using directional antennas to assist the detection of wireless access points. Using an asymmetric model for estimation, our technique can radicalize probability distribution quicker than using a symmetric model. ...
