In this paper an upgraded protocol referred to as Rate Adaptive Sustainable Physical Activity in Neighborhoods (RA-SPAN) protocol is proposed. In this protocol the power saving algorithm of SPAN is integrated with dynamic switching of data rates. Power consumption of nodes is reduced by cross-layer signaling between MAC and Network layers as in the SPAN protocol and dynamically electing the coordinators...
CDMA is most widely used standard for multiuser system in wireless ad hoc network. CDMA standards presents set of protocols for power control, BER control and multiuser detection system in ad hoc network. Therefore behevior of MANET depends upon the modeling of CDMA based MAC layer, which also attributes to the performance of the network. In this paper we present a means of improving the performance...
