Wireless sensor networks (WSN) have lot of interest in research due to their wide range of typical application areas such as environmental, military and commercial enterprises. High efficient routing is an important issue for the design of wireless sensor network (WSN) protocols to meet the severe hardware and resource constraints. Sensor network possesses unique challenges to protocol builders...

Wireless Sensor Networks (WSNs) are vulnerable to clone attacks or node replication attacks as they are deployed in hostile and unattended environments where they are deprived of physical protection, lacking physical tamper-resistance of sensor nodes. As a result, an adversary can easily capture and compromise sensor nodes and after replicating them, he inserts arbitrary number of clones/replic...

Wireless sensor networks (WSNs) are attracting increasing research attention, due to their wide spectrum of applications, including military purposes for monitoring, tracking and surveillance of borders, intelligent transportation systems for monitoring traffic density and road conditions, and environmental applications to monitor, for example, atmospheric pollution, water quality, agriculture,...

Recent research has provided means by which Wireless Sensor Networks (WSN) with dynamic deadlines can make use of mobile agents for data aggregation. Lot of research has already been done with respect to using mobile agents in case of static wireless sensor networks. This paper proposes, along with brief explanation of research issues associated with

BACKGROUND Insulin secretion is a complex and highly regulated process. It is well established that cytoplasmic calcium is a key regulator of insulin secretion, but how elevated intracellular calcium triggers insulin granule exocytosis remains unclear, and we have only begun to define the identities of proteins that are responsible for sensing calcium changes and for transmitting the calcium si...
