chapter
Wireless sensor network is one of the effective tools for data gathering in a variety of environments which has a lot of challenges. Controlling the congestion is one of the challenges that primarily depends on the way the large number of sensors in a network are organized and controlled. A group of nodes is called a cluster which sends information to the gateway through the cluster head. This structure...

Femtocells are aimed at providing strong coverage in the indoor area where typical macrocell coverage is very poor. It has hugely attracted network operators and stakeholders mainly due to its simple plug and play operation and low cost. Femtocells operate on a much lower power compared to macrocell and thus provide a number of benefits including energy efficiency and frequent spatial reuse of the...

The smart grid promises a myriad of benefits for both the consumer and energy service providers. However, realising its potential is subject to solving a number of complex issues. One of the major directions of smart grid research is demand response modelling that aimed at reducing the peak demand and billing by introducing appropriate real time pricing. The main difficulty is in managing the optimum...

While femtocell networks represent a promising solution for extending high data-rate wireless services in indoor environments, despite their many benefits the short coverage distances involved can lead to frequent handovers being triggered resulting in overloading the macrocells. This handover problem is further exacerbated for users operating at the cell boundary. One solution is to keep the mobile station...

Femtocells represent a promising alternative solution for high quality wireless access in indoor scenarios where conventional cellular system coverage can be poor. They are randomly deployed by the end user, so only post-deployment network planning is possible. Furthermore, this uncoordinated deployment creates severe interference to co-located femtocells, especially in dense deployments. This paper...

Femtocells are low-power nodes which aim to extend high data-rate wireless services in indoor environments. While low power operation allows more frequent spectrum reuse and significant improvement in network capacity, it also suffers from frequent handoffs between the macro and femtocell due to the short distances involved. It can potentially generate considerable redundant control data for hand...
chapter
Femtocell access points are inexpensive, plug and play home base stations designed to extend radio coverage and increase capacity within indoor environments. Their inherent uncoordinated and overlaid deployment however, means existing radio resource management (RRM) techniques are often ineffectual. Recent advances in dynamic RRM have emphasised the need for more efficient resource management strategies...
chapter
Femtocells are primarily used to extend high-quality radio coverage in indoor environments. Dense femtocell access point (FAP) deployment however, can lead to severe interference on femtocell user equipment (FUE) from neighbouring FAP, when they operate on the same channel. The problem is compounded as FAP are deployed in an uncoordinated manner by the end-user, which means either avoiding or minimising...
