In Ad Hoc networking, cluster-based communication protocol can reduce large amount of flooding packets in route establishment process. However, the 802.11 medium access control (MAC) protocol is not dedicated to cluster-based network architecture. Applying 802.11 MAC protocol to cluster-based network introduces problems of inefficient channel utilization in announcement traffic indication messa...

Ultimate aim of authors is to implement a high energy efficient data transmission protocol for Mobile Adhoc Networks (MANET) which prolongs the life time of network in a significant way. MANET devices mainly depend on a limited battery power supply to maintain the network with low power consumption techniques by utilizing the available protocol algorithms with enhanced transmission coverage ran...

Wireless adhoc networks are a new type of wireless network which can communicate to each other without infrastructure base stations .Battery power is a vital resource in ad hoc networks. In ad hoc networks, energy consumption does not reveal the communication activities in the network. However, due to restricted power, routing path is broken easily, so how to design an effective power saving ro...

Studies of ad hoc wireless networks are rapidly gaining popularity due to its varied and innovative applications. Medium Access Control (MAC) protocols in such networks are responsible to coordinate access among active nodes. Wireless nodes are largely powered by batteries which restricts the quantity of energy available to the nodes. Routing for wireless nodes is incorporated with power saving...

Power is always a major concern for mobile devices. To save precious energy, mobile devices choose to stay in a low power mode by turning off their transceivers when it is not involved with transmission. However, they need to wake up to allow packets originated from them sent and those coming to them received. This presents a challenge in the distributed environment as in ad hoc networks. In th...

This paper presents a protocol which improves on the power saving mechanism in the IEEE 802.11 Distributed Coordination Function (DCF). In the power saving mechanism (PSM) for DCF, all nodes are synchronized by beacons. In each beacon interval, there is a fixed time interval called the ATIM window where every node has to be awake. During the ATIM window, a source node informs a destination node...

Ad hoc routing technology has been developed primarily for networks of mobile nodes. The operational life of untethered nodes will be limited by its power source, so ad hoc networks strongly depend on the efficient use of their batteries. All the layers of communication are coupled in power consumption and solutions addressing the power saving issue include transmission power control, power awa...
