基于混合粒子群算法的TSP寻优算法
粒子群算法虽然具有算法简单,寻优速度快等优点,但同时存在算法容易收敛,易陷入局部最优值等问题。采用遗传算法改进粒子群算法,通过选择、交叉和变异操作的引入,改进了算法性能,增强了算法的全局搜索能力。本案例研究了基于混合粒子群算法的TSP寻优算法。

A Reader Anti-collision Protocol for RFID-Enhanced Wireless Sensor Networks
资源描述Abstract Considering rapid developments in the technologies of both radio-frequency identification
(RFID) systems and wireless sensor networks (WSN), an integration of the two
technologies may lead to the formation of an RFID-enhanced WSN which would possess
improved functions and capabilities. In the RFID-enhanced WSN, many reader-enhanced
nodes have increasingly been employed. In such networks, RFID data contains a lot of duplication,
because the same tag may be read multiple times, and collision may occur among
readers, while energy constraints are also a serious problem. These three could in turn cause
serious problems. In this paper, we have proposed our CSMA-based algorithm since it is light,
efficiently minimizes all kinds of reader collision, and eliminates the duplicate data. For this
purpose, we have used a separate control channel and a tag ID forwarding mechanism with a
special co
