Abstract
A broadcasting protocol for a wireless sensor network needs to be simple, lightweight and robust. The main goal of a broadcasting protocol is to gain the best propagation of a message for the low- est energy consumption. This is hard to achieve as typically sensor networks have low energy reserves and turbulent wireless transmis- sion, making them extremely prone to failure. PAMPA and Smart Gossip are the two broadcast protocols compared in this paper, their performances in previous simulations are amongst the best in the current research area. This is determined by how successfully they deliver packets to each node on the network and more importantly how little energy they consume while doing this. It is also important to evaluate how they perform when they are subject to real network problems such as node, message and sending failure. Before ei- ther protocol can be recommended for deployment, it is important to find how well they perform when deployed on a real network. By comparing the two protocols on a real network we can find the most lightweight, efficient and robust protocol when used in real life. This paper discusses the benefits and drawbacks of the two protocols, presents an in-depth evaluation and establishes which is the most capable. The results of this paper conclude that PAMPA was by far the most effective broadcast protocol; it managed to de- liver a high percentage of messages to each node on the network and managed to keep its message retransmissions and therefore its energy consumption very low.
