This work proposes two enhanced multiple mobile subscriber stations (MSSs) power-saving scheduling methods for IEEE802.16e broadband wireless networks. The proposed methods are designed for the Unsolicited Grant Service (UGS) of IEEE802.16e. To reduce the active periods of all power-saving MSSs, the base station (BS) allocates each MSS fewest possible transmission frames to retrieve its data from the BS. The BS interlaces the active periods of each MSS to increase the amount of scheduled MSSs and splits the overflowing transmission frames to maximize the bandwidth utilization. Simulation results reveal that interlacing the active periods of MSSs can increase the number of scheduled MSSs to more than four times of that in the Direct scheduling method. The bandwidth utilization can thus be improved by 60%–70%. Splitting the overflowing transmission frames can improve bandwidth utilization by more than 10% over that achieved using the method of interlacing active periods, with a sacrifice of only 1% of the sleep periods in the interlacing active period method.

Ad-hoc networks consist of a set of mobile nodes with a restricted power supply resources that can communicate with each other without any established infrastructure or centralized administration. The loss of some nodes may cause significant topological changes, undermine the network operation, and affect the lifetime of the network. This paper discusses the energy consumption problem and summaries the existing power saving techniques in ad-hoc wireless networks. The main objective of this paper is to introduce a new power aware multi-path node disjoint routing scheme based on the Dynamic Source Routing protocol (DSR), which can prolong MANETs lifetime, reduce routing delay and increase the reliability of the packets reaching its destination. Therefore, a comprehensive study of DSR protocol has been drawn using NS-2 simulator, to evaluate the performance of DSR as a routing strategy and investigate its efficiency in saving wireless networks resources, as a prelude to avoid its performance shortcomings in our proposed routing scheme. Keywords: Power aware protocol, node disjoint, network simulation 2, multipath routing, Dsr protocol, ad-hoc network.
