Machine-to-machine (M2M) communications consist of a large number of smart devices that communicate automatically without human intervention. The Third-Generation Partnership Project (3GPP) Long-Term Evolution (LTE) and LTE-Advanced (LTE-A), due to some features such as IP connectivity and scalability, are ready-to-use infrastructures for the M2M communications implementation. In the next generation...
In recent years, the usage of data is more than available resources. Due to fast growing requirements and development of the green communication technology may lead to go for many energy saving designs in networks, the faster growing network is LTE(4G), which is going to give more traffic, because of the user requirements, so the issues in the mobile networks are (1) traffic in networks (2) more energy...
The performance of cooperative communications is highly dependent on careful resource allocation such as relay selection. Considering individual QoS requirements in a multi user system, traditional cross-layer relay selection schemes, failed to achieve an acceptable level of fairness considering limited buffer capacity of relays. To address this problem, in this paper, we propose a buffer management-based...
In a resource constrained wireless sensor network (WSN), communication tasks can be expensive in terms of power consumption. Thus, when good communication is required, a mechanism that can maximize the chances of a successful transmission of information via wireless network is very desirable. The Opportunistic Routing (OR) protocol has been proposed as an alternative and efficient method for exploiting...
