Homomorphic Filtering for Improving Time Synchronization in Wireless Networks
Wireless sensor networks are used to sample the environment in a distributed way. Therefore, it is mandatory for all of the measurements to be tightly synchronized in order to guarantee that every sensor is sampling the environment at the exact same instant of time. The synchronization drift gets bigger in environments suffering from temperature variations. Thus, this work is focused on improvi...
متن کاملSimple Algorithm for Improving Time Synchronization in Wireless Sensor Networks
We present a simple method for improving time synchronisation suitable for use in ad-hoc sensor networks where processing power is limited. The technique is local and uses Bayesian estimation. A simple simulation shows an improvement of an about four times.
متن کاملTime Synchronization in Wireless Networks
Time Synchronization in wireless networks is extremely important for basic communication, but it also provides the ability to detect movement, location, and proximity. The synchronization problem consists of four parts: send time, access time, propagation time, and receive time. Three current synchronization protocol Reference Broadcast Synchronization, Timing-sync Protocol for Sensor Networks,...
متن کاملTime Synchronization in Wireless Sensor Networks 253 Time Synchronization in Wireless Sensor Networks
Recently small smart devices start to be embedded into the various environments in order to monitor the events occurred in the areas such as homes, plantations, oceans, rivers, streets, and highways. These tiny and low power devices which enable sensing and communication tasks have made sensor networks emerged. In wireless sensor networks (WSNs), especially, wireless devices get together and sp...
متن کاملTime Synchronization for Wireless Sensor Networks
With the help of recent technological advances in micro-electro-mechanical systems (MEMS) and wireless communications, low-cost, low-power, and multifunctional wireless sensing devices have been developed. When these devices are deployed over a wide geographical region, they can collect information about the environment and efficiently collaborate to process such information by forming a distri...
