Study of Wireless Sensor Network Location Algorithm and Data Collection Protocol

Abstract

Abstract-It is deduced that the network life time is inversely proportional to the zone area of the collection data that each sink is responsible for. That is to say, when the zone area in the charge of a sink is smaller, the average load of nodes distributed in this area and the energy consumption are smaller, while the network life time is longer. MSGP protocol is proposed, with several round cluster head candidate zones, fixed member zones and public zones being delimited to make approximately uniform clustering. The cluster head is responsible for collecting a meaningful event in the cluster, making data fusion and then forwarding it to sink. Multi-sinks move according to the zone division rules and the rule of free movement. Specific analysis is made from three aspects of data direction, single round data collection of sink, and network life time.

Performance Analysis of Wireless Location and Velocity Tracking of Digital Broadcast Signals Based on Extended Kalman Filter Algorithm

“…With the development of technology, terrestrial broadcasting, as a new information transmission technology, has begun to be widely used, and the wireless system based on this technology has also begun to build on a large scale, and a new passive positioning technology based on broadcast signal has also begun to be proposed and has attracted more and more attention of researchers at home and abroad [21,22]. ere are many advantages and potential advantages in wireless passive location using broadcast signal.…”
