There are a huge number of papers considered communication activity in WSN, related mainly to clustering and routing problems. On the one hand, scientists have discussed sensors' self-configuring [1], self-management [3, 1, 19], adaptive clustering [1, 9, 22] or concept of adjustable autonomy [5]. On the other hand, there are papers which discuss bio-inspired ideas and tend to extract some aspects of the natural world for computer emulation [6].

The WSN communication structure is crucial for BS migration. Authors [4] have shown that the communication topology of some biological, social and technological networks is neither completely regular nor completely random but stays somehow in between these two extreme cases. It is worth to mention papers [22, 19, 3] devoted to self-organizing protocols using both random and deterministic elements.

In order to effectively manage communication activities, one has to address the problems of sensor network organization and the subsequent reorganization and maintenance [22].
