Abstract
Due to its efficiency in end-to-end communication, wireless sensor network based on the Internet protocol (IP-WSN) is used for monitoring purposes. Nowadays, the concerned agencies are giving their highest priority to monitor its critical infrastructure. Infrastructure health monitoring is the measure of estimating the state of infrastructure health or detecting the changes in structures that affect its performance. The traditional approach to monitor the infrastructure health is done by using centralized data acquisition hub. Installation and commissioning of these systems represent significant concerns, thus moving toward IP-WSN. As cost effectiveness and energy efficiency are major concerns, our proposed approach is to reduce the amount of overhead while keeping the infrastructure health monitoring system accurate. Our contribution in this paper is to reduce the amount of data to be transmitted by compressing the payload of the packets. Thus, we have proposed a double compression algorithm. In this way, the capacity of the sensor node will be increased since less time will be taken to transmit data between the intermediate node as well as the coordinator node. As a consequence, it will also extend the lifetime of the battery.

Summary
Wireless sensor network (WSN) consists of a varying number of tiny sensor nodes It is distributed in a wide geographical area based on the nature of application. The traditional approach for infrastructure health monitoring involves conventional piezoelectric accelerometers and other sensor nodes connected to data collection boards. Despite all the advantages of the wireless system, it still requires end-to-end communication for monitoring the infrastructure and a better compression algorithm for IP payload. We propose an efficient payload compression for infrastructure health monitoring in WSN. End-to-end communication of IP-WSN is a promising tool for IHM, especially in critical infrastructure where human intervention is almost impossible In this regard, IPv6-based low-power wireless personal area network (6LoWPAN) provides a unique opportunity [9].
