Abstract

Two hybrid handshaking schemes based on the receiver-initiated concept and spread spectrum techniques are proposed for spread spectrum mobile ad hoc networks. In these schemes, called Receiver-Initiated Multiple Access Common-Transmitter-Based (RIMA/C-T) and Receiver-Initiated Multiple Access Receiver-Transmitter-Based (RIMA/R-T) protocols, the polling node allows the polled node to transmit a message to the polling node itself first after it acquires a channel successfully. The proposed schemes are the extensions of previous works [1]. Under a general analytic model, throughput and message delay of the proposed schemes are evaluated. Theoretical and simulation results show that the proposed schemes achieve better performance than Multiple Access with Collision Avoidance Common-Transmitter-Based (MACA/C-T) and Multiple Access with Collision Avoidance Receiver-Transmitter-Base (MACA/R-T) protocols proposed in earlier literature [1].
