Abstract
This paper presents a novel method of modeling spatialcommunication activity in wireless sensor network(WSN). We define native aspects of communication inWSN. Focusing on local/global activity dilemma,cooperation, interference, network topology, andoptimization aspects. A neighborhood abstraction isdefined and we involve three binary relations:subordination, tolerance and collision to describe thecooperation in WSN. Using digital terrain model toolswe model communication activity aspects as surfaces,stretched over WSN network. A network topologyfeatures are modeled using bare drainage surface. It is acomponent of a topographic map, which gives adirection towards the base station, determined by aslope of the modeled surface. Modeling node?s instantenergy level, we construct another surface representsnode?s instant level of consumed energy. Finally, weconstruct a drainage surface spread over each nodeneighborhood as superposition of bare drainage surface,energy consumed and relational surfaces.
