A simulation framework for evaluating complete reprogramming solutions in wireless sensor networks

Abstract

Abstract-We propose a simulation framework developed in Simulink for analyzing the performance of code dissemination in wireless sensor networks. The complete solution relies on a three-layer network stack where the LMAC, FixTree and RMD protocols operate in conjunction. For performance evaluation, we use in our simulations the radio link quality model derived from previous field trials. In this way, we can study the impact of real network conditions (e.g. fluctuating link quality, changing neighborhood) on the higher layer protocols and thus verify our design choices in non-idealized circumstances.

A Review on Reprogramming Approach in Wireless Sensor Nodes

“…Other ways to enhance reliability include the adoption of forward error correction (FEC) to avoid (to the extent possible) retransmissions or use link quality estimates to improve decisions or even use fountain codes to transmit data. The performance metrics reflecting the target of the dissemination protocols [7] include efficiency in terms of overhead (its reduction directly translates to better utilization of the low available throughput) and of energy (which affects the network lifetime, an important parameter in this mainly battery operated environment) as well ISSN: 2319 -1058 the time required to detect that an update is needed and the time required to disseminate the update throughout the network.…”

Distributed and self-organizing data management strategies for wireless sensor networks

“…Before describing how we analyze the cost of tree-based flooding (TBF), we first explain how a TBF operation is carried out in order to justify the analysis later on. We make the assumption that a tree building/maintenance protocol such as FixTree [106] is used to set up a communication tree. Using this protocol in combination with LMAC, every node would know which adjacent node is its parent node, which adjacent nodes are child nodes and which nodes are neither parent or child nodes.…”
