Abstract
Time Synchronization is one of the problems and still ignored problem in area of wireless sensor network (WSN). After reviewing the existing literatures, it is found that there are few studies that combinely address the problem of energy conservation, clustering, routing along with minimizing the errors due to time synchronization in sensor network. Therefore, this manuscript presents a delay-based routing which considers the propagation delay to formulate a mechanism for delay compensation in large scale wireless sensor network. The prime goal of this technique is to jointly address energy problems, time synchronization, and routing in wireless sensor network. The outcome of the proposed study was found to posse’s minimized communication overhead, minimized synchronization errors, lower energy consumption, and reduced processing time when compared with the existing standards of time synchronization techniques.
Highlights
Wireless sensor network is increasing finding its utility in unmanned monitoring system over hazardous geographical locations [1]
This section discusses about the existing studies being carried out in the problem area of time synchronization pertaining to wireless sensor network
The prime aim of the proposed study is to formulate a novel optimization technique that can combinely address the problem of i) time synchronization, ii) enhancement of network lifetime, and iii) data aggregation for large scale wireless sensor network
Summary
Wireless sensor network is increasing finding its utility in unmanned monitoring system over hazardous geographical locations [1]. Time synchronization plays an important role in wireless sensor. The problems start shooting when the sensor present in the environment start exhibiting different local time with higher difference in their values. The two sensors sense the same event at same time but time stamps it with different value Such problem gives rise to all sort of data quality issues that poses a potential threat to both communication performance as well as security [4][5]. In order to study time synchronization, various research work have been already carried out in the last decade. There is various applications where time synchronization plays a critical role in delivering quality services e.g. healthcare.
