An analytical model for lifetime of hierarchical wireless ad hoc and sensor networks

J. Martyna

Abstract


This paper presents an analytical model for lifetime of hierarchical wireless ad hoc and sensor networks based on energy by considering the relationship between individual nodes, cluster of nodes and the whole network. The model uses a set of hardware parameters such as data-rate, minimum required transmit power, etc. to compute a node's average lifetime in these networks. Through comparison of the lifetime model of hierarchical and flat topologies for ad hoc and sensor networks we shown how these models can be applied to drive architectural decisions, compute energy budgets, etc. This allows designers of ad hoc and sensor networks to focus on factors that have the greatest potential impact on network lifetime.
