The criticality of survivable network design and operation increases with increasing transmission speed. Path protection strategies achieve better network utilization compared to link protection strategies; however the recovery time of connections in path protection strategies are higher than that in link protection strategies. This paper develops a new(More)
Cellular network service providers are trying to expand their capacity to accommodate the increasing mobile traffic demand by adopting new mobile technologies like user proximity based Device-to-Device (D2D) communication underlying existing Long Term Evolution-Advanced (LTE-A) cellular network, which is a promising technology to overcome legacy cellular(More)

Energy saving is an essential issue in the design of a wireless sensor network because the sensor nodes are generally energy-limited. Thus, minimizing and balancing the energy consumption for nodes are becoming important in terms of extending the network lifetime. In this paper, a novel energy-efficient cooperative MIMO transmission mechanism based on(More)
