CRSN Energy-Efficient Mechanism Based on Dynamic Spectrum Access and Asynchronous Sleep-Wake Scheduling
… two strategies: Sensor-Medium Access Control (S-MAC) protocol and the K-Means clustering algorithm. These strategies are designed and implemented in the CRSN to improve the existing energy-aware mechanism and to minimize high energy consumption. K-Means clustering reduces the overall network …

MAC and physical layer energy efficiency for ad hoc wireless sensor networks
… a new, energy efficient Medium Access Control (MAC) layer for Ad Hoc Wireless Sensor Networks (AHWSN). MAC solutions are either contention based or non-contention based. Energy inefficiencies in contention based MAC protocols suffered from collisions, overhearing, control overhead and idle …

Denial-of-Sleep Vulnerabilities and Defenses in Wireless Sensor Network MAC Protocols
… sensor network medium access control (MAC) protocols that leave them susceptible to denial-of-sleep attack. It then classifies these attacks in terms of an attacker's knowledge of the MAC layer protocol and ability to bypass authentication and encryption protocols. Attacks from each …

Using routing information to improve MAC performance in multi-hop wireless networks
… However, traditional contention-based wireless MAC protocols such as IEEE 802.11 DCF are designed for single-hop wireless networks and do not perform well in multi-hop scenarios due to inefficiency in their medium reservation mechanisms. In this thesis, a new general mechanism, utilizing a new …

Design and analysis of energy-efficient media access control protocols in wireless sensor networks. Design and analysis of MAC layer protocols using low duty cycle technique to improve energy efficient and enhance communication performance in wireless sensor networks.
… concerns are managed by medium access control (MAC) layer protocols. MAC protocols designed specifically for WSN have an additional responsibility of managing radio activity to conserve energy in addition to the traditional functions. This thesis presents advanced research work carried out in …
