Internet Protocol version 6 (IPv6) over Low power Wireless Personal Area Networks (6LoWPAN) is extensively used in wireless sensor networks (WSNs) due to its ability to transmit IPv6 packet with low bandwidth and limited resources. 6LoWPAN has several operations in each layer. Most existing security challenges are focused on the network layer, which is represented by its routing protocol for low-power...
A Wireless Sensor Network (WSN) is a network of thousands of low-cost sensors which have a limited operating lifetime. A sensor node generally comprises four basic elements, including a transceiver unit, a detection unit, a processing unit, and an energy supply unit. One of the major challenges in the WSN is to increase the network life-time. Since the transmitting/receiving unit has the highest energy...
To meet the requirements of wearable wireless sensor networks (W-WSN), the power dissipation of the RF transceiver has to be drastically reduced.

In this article, we propose to use game theory to model our WSN network. In this setting, the goal of the compromised node is to keep disrupting the network while remaining alive. The game studied is a two-player quantitative infinite game on a finite graph, where each transition can change some energy levels and some reward. The goal of the compromised node is hence to maximize its reward while maintaining...
The role of energy in wireless sensor networks (WSN) becomes very important when network is unattended and it is not possible to recharge sensor node's battery in the sensing region many times. Due to this limited battery energy of sensor nodes it becomes a challenge for WSN to maintain proper functioning for a long time. So for the enhancement in network lifetime of the WSN, here we propose a modified...
