Carrier Sense Multi-Access (CSMA) is a typical method to share the common channel in a Wireless LAN (WLAN). It works fairly well in times of light traffic. However as the number of...
— In multihop wireless networks where a random access MAC scheme such as CSMA/CA is used, nodes greedily compete in a distributed manner and are unaware of the interference they ...
To achieve security in wireless sensor networks, it is important to be able to encrypt and authenticate messages sent among sensor nodes. Keys for encryption and authentication pu...

A wireless sensor network (WSN) is envisioned as a cluster of tiny power-constrained devices with functions of sensing and communications. Sensors closer to a sink node have a larg...
Key predistribution in wireless sensor networks refers to the problem of distributing secret keys among sensors prior to deployment. Solutions appeared in the literature can be cl...
