Research has revealed that the correlation between distance and RSSI (Received Signal Strength Indication) values is the key of ranging and localization technologies in wireless sensor networks (WSNs). In this paper, an RSSI model that estimates the distance between sensor nodes in WSNs is presented. The performance of this model is evaluated and analyzed(More)
The next generation 5G radio access network (RAN) system is believed to be a true world wide wireless web (WWWW). This is because such system will seamlessly and ubiquitously connect everything, and support at least 1000-fold traffic volumes, 100 billion connected wireless devices, and diversified use cases as well as quality of service (QoS) requirements(More)
Third generation (3G) cellular networks are being implemented in many countries at high rate. Due to the fact that manual cell planning is a time consuming process and prone to a degree of error and inefficiency, there is a need for automated approaches to optimise coverage, capacity and quality of cellular networks in a fraction of the time. This paper(More)
Wireless channels operate through the transmission of electromagnetic signals from the transmitter to the receiver. In a fixed wireless network, the transmission medium is often distorted or disrupted by inherent natural phenomenon which in turn corrupt, obstruct or cause most of the data transmitted over the channel to generally get garbled. In a vehicular(More)
A considerable amount of energy is consumed during transmission and reception of messages in a wireless mesh network (WMN). Reducing per-node transmission power would greatly increase the network lifetime via power conservation in addition to increasing the network capacity via better spatial bandwidth reuse. In this work, the problem of topology control in(More)
The energy consumption is a key design criterion for the routing protocol in wireless sensor networks. Some routing protocols deliver the message by point to point like wire networks, which may not be optimal to maximise the lifetime of the network. In this paper, a competing algorithm for GBR in wireless sensor networks is proposed. This algorithm is(More)
Internet protocol multimedia subsystem (IMS) was introduced by the third generation partnership project (3GPP) as a horizontal application platform necessary to address the need for a new platform with unified features, common elements, quality of service, open standardized interface for all existing and future multimedia applications and services. IMS is a(More)
Localisation is one of the most important applications for wireless sensor networks since the locations of the sensor nodes are critical to both network operations and most application level tasks. Numerous techniques for localisation of sensor nodes that make use of the Received Signal Strength Indicator (RSSI) have been proposed because of the simplicity(More)
The increasing size and complexity of telecommunication databases poses a significant challenge for conventional data mining approaches. As mobile networks mature, greater pressure is placed on network operators to make their networks more competitive. This paper proposes the use of matrix decomposition methods for the improvement of data mining in(More)
