Security is a very important requirement in networks and wireless sensor network are no exception to this. During security attack, an attacker can inject an intruder node in the network which can alter the data being disseminated or modify the data item too. So towards overcoming this issue, security protocol called Didrip was developed for flat based network which allows for distributed data discovery...
Forest is one of the most valuable and indispensible natural resource. The forest fire is one of the natural disasters that destroy the forest not only in India but countries like Australia, USA etc which is called as bush fire, wild fire respectively. Now in terms of deploying Wireless Sensor Networks for forest fire monitoring and detection, there is a need to investigate appropriate routing protocol...
We present an approach to detect a selfish node in a wireless network by passive monitoring. This does not require any access to the network nodes. Our approach requires deploying multiple sniffers across the network to capture wireless traffic traces among multiple channels. IEEE 802.11 networks support multiple channels, and a wireless interface can monitor only a single channel at one time. Thus,...
One of the most important parameters to be studied in Wireless Sensor Networks (WSNs) is its life time. There are two typical data mining processes that support to reduce the energy consumption of WSNs is clustering and data summarization. Several energy aware, communication aware, coverage aware, data dissemination and data aggregation/sensor fusion protocols and algorithms have been specifically...
There is presently considerable research interest in using wireless and mobile technologies in patient health monitoring particularly in hospitals and nursing homes. For health monitoring, an intelligent agent based hierarchical architecture has already been published by one of the authors of this paper. Also, the technique of monitoring and notifying the health of patients using an intelligent agent,...
