Abstract— The IEEE 802.11e standard has recently been ratified. This standard provides Quality-of-Service (QoS) guarantees in the Medium Access Control (MAC) layer of 802.11 Wir...
The ns-2 simulator has limited support for simulating 802.11based wireless mesh networks. We have added the following new features at the MAC and PHY layer of ns-2: (i) cumulative...
Abstract. Providing energy efficiency in MAC (Medium Access Control) layer, while achieving desirable throughput, is an important research issue in the area of wireless networking....
—Duty-cycle MAC protocols have been proposed to meet the demanding energy requirements of wireless sensor networks. Although existing duty-cycle MAC protocols such as S-MAC are p...
—Localization is a fundamental problem in wireless sensor networks and its accuracy impacts the efficiency of location-aware protocols and applications, such as routing and stora...
