Abstract
It is known that grouping nodes gives better performance to the group and to the whole system, thereby avoiding unnecessary message forwarding and additional overheads while allows to scale the network considerably. Many routing protocols for ad-hoc networks and sensor networks have been designed, but none of them is based on groups. In this paper, after a review of group based architectures and of neighbor selection strategies, a planar group-based network architecture is proposed. In the proposal, the network is formed by several groups of ad-hoc devices or sensors. Connections between groups are established as a function of the proximity and the neighbor's available capacity (based on the ad-hoc device or sensor’s energy). The messages that are needed to the proper operation are shown. It is also simulated how much time is needed to propagate information between groups and it is calculated the diameter for different topologies
