— Group communications are important in Mobile Ad hoc Networks (MANET). Multicast is an efficient method to implement the group communications. However, it is challenging to imp...
Abstract--There has been a great deal of attention on cooperative communication which exploits the spatial diversity among antennas belonging to multiple terminals. Most of the exi...
—It is well known that IEEE 802.11 provides a physical layer multirate capability and, hence, MAC layer mechanisms are needed to exploit this capability. Several solutions have b...
This paper presents Random Asynchronous Wakeup (RAW), a power saving technique for sensor networks that reduces energy consumption without significantly affecting the latency or c...
—The majority of security protocols employ public key cryptography for authentication at least in the connection setup phase. However, verifying digital signatures is an expensiv...
