“…3) Intelligence: Intelligent systems can also be integrated to the WSN paradigm to equip the sensors with the ability to continuously monitor the patient or perform an event driven surveillance. 4) Transmission power: The transmit power used by the sensors should be very low to prevent interference and radiation [93,92], which could be harmful to a person. However, the power should also be enough to provide power for sensing.…”

A Wireless sensor network consists of many devices called as sensor nodes which communicate with each other, to sense the parameters of the environment in which they have been deployed. Sensor nodes communicate with each other using wireless communication techniques and these techniques are governed by routing protocols. Traditional routing protocols cannot be used in WSNs because of the inherent nature of WSNs that distinguishes it from other wireless networks. Performance of the Wireless sensor network depends on the routing protocol hence an extensive survey of the challenges and issues faced during the design of the routing protocols is presented in this paper. Major categories of routing protocols are discussed in detail in this paper. Energy efficient routing protocols are emphasized further.

“…To meet this requirement, indoor localization systems based on wireless sensor networks (WSNs) have been developed [1][2][3]. The WSNs are a kind of self-organizing network composed of many nodes with wireless transceivers, microprocessors, and sensors [4][5][6]. The received signal strength indication (RSSI) is the easiest to measure by a wireless transceiver, so it is often used to estimate distances and locations between nodes [7][8][9].…”

The Global Positioning System (GPS) is unable to provide precise localization services indoors, which has led to wireless sensor network (WSN) localization technology becoming a hot research issue in the field of indoor location. At present, the ranging technology of wireless sensor networks based on received signal strength has been extensively used in indoor positioning. However, wireless signals have serious multipath effects in indoor environments. In order to reduce the adverse influence of multipath effects on distance estimation between nodes, a multi-channel ranging localization algorithm based on signal diversity is herein proposed. In real indoor environments, the parameters used for multi-channel localization algorithms are generally unknown or time-varying. In order to increase the positioning accuracy of the multi-channel location algorithm in a multipath environment, we propose an optimal multi-channel trilateration positioning algorithm (OMCT) by establishing a novel multi-objective evolutionary model. The presented algorithm utilizes a three-edge constraint to prevent the traditional multi-channel localization algorithm falling into local optima. The results of a large number of practical experiments and numerical simulations show that no matter how the channel number and multipath number change, the positioning error of our presented algorithm is always smaller compared with that of the state-of-the-art algorithm.
