The exponential growth in data traffic and dramatic capacity demand in fifth generation (5G) have inspired the move from traditional single-tier cellular networks toward heterogeneous cellular networks (HCNs). To face the coming trend in 5G, the high availability requirement in new applications needs to be satisfied to achieve low latency service. Usually, these applications require an availability...
The exponential growth in data traffic and dramatic capacity demand in fifth generation (5G) has inspired the move from traditional single-tier cellular networks towards heterogeneous cellular networks (HetNets). To face the coming trend in 5G, the high availability requirement in new applications, needs to be satisfied to achieve low latency service. In this work, we present a tractable multi-tier...
The vast majority of researches about the shortest path algorithm, nowadays, focus just on the case starting from the beginning point and ending at the ending point. If additional condition that the shortest path must go through some given nodes of which number is uncertain must be met, then most of the existing classic algorithms are not applicable. A general method based on the Virus Co-Evolutionary...
Resource allocation plays an important role for the performance of cognitive radio based wireless mesh networks that are capable of multiple channel access. In order to maximize the entire network throughput, the interference aware resource allocation model including channel assignment and link scheduling to satisfy all routing requirements is presented. A novel genetic algorithm based channel assignment...
One of the most critical issues in wireless sensor network is represented by the limited availability of energy on sensor nodes. In this paper, we propose the power efficient organization of k-separate cover sets as a backbone to maximum network lifetime. All the sensors are divided into K-separate sets on the basis of multi-objective genetic algorithm, guaranteeing each cover set is pareto optimal...
Wireless sensor networks (WSN) constitute the platform of a wide application related to military, remote monitoring, inhospitable physical environment, and national security. Reducing energy consumption to extend network lifetime is one of the most important requirements in designing wireless sensor networks. Keeping only a minimal number of sensors active and putting others into low-power sleep mode...
