Abstract
This paper presents an analysis of the impact of shadow fading on the performance of TDMA slot allocation, with latter being measured in terms of the resultant in-network interference versus spatial reutilization. Simulations are presented which demonstrate that for Wireless Sensor Networks operating in shadow fading channels, protocols that feature TDMA slot allocation based on channel probing, e.g. LEMMA, lead to a significantly lower interferences when compared with protocols based on the n-hop neighborhood criterion. An extension of the basic LEMMA protocol is also presented, which leads to almost zero interferences.
