Topology characterization of wireless sensor networks is a key issue for network planning, management and control as well as for maximizing the network performance and for optimizing protocol design. In this paper we analyze the structure of the topologies formed by means of the IEEE 802.15.4 association procedure, i.e., trees rooted at sink nodes, and we verify how such structures affect the network performance. Specific attention is dedicated to understand how the network lifetime is affected by the type of topology formed during the network set-up. A comparison of topologies having a single sink and multisink ones is provided. The determination of performance in case of multi-sink scenarios is extremely important; nevertheless, to the best of our knowledge, this problem is tackled here for the first time as for IEEE 802.15.4.

Abstract
Topology characterization of wireless sensor networks is a key issue for network planning, management and control as well as for maximizing the network performance and for optimizing protocol design. In this paper we analyze the structure of the topologies formed by means of the IEEE 802.15.4 association procedure, i.e., trees rooted at sink nodes, and we verify how such structures affect the network performance. Specific attention is dedicated to understand how the network lifetime is affected by the type of topology formed during the network set-up. A comparison of topologies having a single sink and multisink ones is provided. The determination of performance in case of multi-sink scenarios is extremely important; nevertheless, to the best of our knowledge, this problem is tackled here for the first time as for IEEE 802.15.4.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
