The performance of point-to-point routing protocols is limited by a trade-off between routing state and routing stretch. A wireless sensor network (WSN) designer can choose from a whole spectrum of routing techniques that exploit this trade-off at varying granularity. We aim to make such choices more informed; our contributions are twofold. First, we present the first point-to-point routing framework...
A recursive multihop area hierarchy has a number of applications in wireless sensor networks, the most common being scalable point-to-point routing, so-called hierarchical routing. In this paper, we consider the problem of maintaining a recursive multihop area hierarchy in large sensor networks. We present a gossip-based protocol, dubbed PL-Gossip, in which nodes, by using local-only operations and...
We consider multi-resolution storage, a technique for providing scalable adaptive data fidelity, necessary for many applications of large wireless sensor networks (WSNs). Although the previously proposed design of multi-resolution storage, based on quad trees and geographic routing, is conceptually simple, it exhibits inherent problems if applied to real-world WSNs. To address these problems, we revisit...
Hierarchical routing is a promising approach for point-to-point routing with very small routing state. While there are many theoretical analyses and high-level simulations demonstrating its benefits, there has been little work to evaluate it in a realistic wireless sensor network setting. Based on numerous proposed hierarchical routing infrastructures, we develop a framework that captures the common...
PL-Gossip is evaluated using packet-level event-driven simulator. Experiments are conducted with varying network sizes, densities, message loss rates, and node arrival and departure schemes . The experimental results verified that a node's state, as maintained by the protocol (i.e., the label and the routing table), grows logarithmically with the network size, which ensures scalability and small bandwidth...
