Wireless sensor network is typically used to detect and monitor various types of objects in real-time monitoring area in which security is one major challenge. Evaluation of nodes' trust is proven to be an effective solution of improving security, supporting decision-making and nodes collaboration in both wired and wireless networks. However, existing approaches of trust management emphasize mostly...
LEACH is one classical protocol in wireless sensor network, which is a clustering-based protocol with good performance. In this paper, an improved routing algorithm based on LEACH protocol will be proposed, which involves cluster head choosing, multi-hop routing and the building of its path. Simulation in MATLAB, an improved routing algorithm has higher energy utilizing rate, and it helps prolong...
In wireless sensor network, we have 2 type of routing; one of them send data from the sensor nodes to the sink and another send some data from sink to the sensor nodes such as programming/retaking binaries, queries and commands. In this paper we present a new routing algorithm base on ID that is named ID-Leach. This protocol assigns an unique ID with binary number to each sensor nodes. This protocol...
