— Several problems are required to be fixed in order to apply geographical routing protocol Greedy Perimeter Stateless Routing (GPSR) in wireless sensor networks. First, GPSR is...
—Data collection is one of the major traffic pattern in wireless sensor networks, which requires regular source nodes to send data packets to a common sink node with limited end...
This paper examines the denial of service attacks that an 802.16 Broadband Wireless Access network is susceptible to at the physical and medium access control layers. In our threa...
In query-based wireless sensor networks (WSNs), the system must perform data sensing and retrieval and possibly aggregate data as a response at runtime. Since a WSN is often deplo...
Energy efficiency is one of the crucial design criteria for wireless sensor networks. Idle listening constitutes a major part of energy waste, and thus solutions such as duty cycli...
