An analytical model for IEEE 802.15.4 non-beacon enabled CSMA/CA in multihop wireless sensor networks

In this paper we propose a new analytical model for the IEEE 802.15.4 non-beacon enabled CSMA/CA. Previous models often assume that the probability of channel busy assessment is independent of the back-off stage. We show that this condition does not hold for the IEEE 802.15.4 and propose a modeling approximation. In our analysis, we consider multihop topologies and unsaturated traffic. We discu...

Energy Detection in Multihop Cooperative Diversity Networks: An Analytical Study

This work presents a study of detection performance of energy detector in relay based multihop cooperative diversity networks operating over independent Rayleigh fading channels. In particular, upper bound average detection probability expressions are obtained for three scenarios: (i) Multi-hop cooperative relay communication; (ii) Multi-hop cooperative relay communication with direct link and ...

Analytical modeling of self-pruning and an improved probabilistic broadcast for wireless multihop networks

The first wave of broadcasting algorithms exploit neighbor knowledge to reduce redundant retransmissions in mobile ad hoc wireless networks (MANETs). Self-pruning is one of such broadcast algorithm that received much attention from the research community. In self-pruning, only a subset of nodes forward the message based on certain forwarding rule. Moreover, it belongs to one of the reliable bro...
