This paper presents two efficient flooding algorithms based on 1-hop neighbor information. In the first part of the paper, we consider sender-based flooding algorithms, specifically the algorithm proposed by Liu et al. In their paper, Liu et al. propose a sender-based flooding algorithm that can achieve local optimality by selecting the minimum number of forwarding nodes in the lowest computational...
Topology control is an effective method to improve the energy efficiency of wireless sensor networks (WSNs). Traditional approaches are based on the assumption that a pair of nodes is either "connected" or "disconnected". These approaches are called connectivity-based topology control. In real environments however, there are many intermittently connected wireless links called lossy...
In this paper, we propose a new multicast subgraph construction algorithm and a distributed source coding-based multicast (DSCM) protocol for multihop wireless networks. The DSCM emphasize reliability, rate optimality, and energy efficiency. Both algorithms are based on local knowledge of the network. DSCM uses rateless error correcting codes to provide reliability and rate optimality, and distributed...
