Energy harvesting has drawn more and more attention because of the requirement of the green communication. It is well known that energy harvesting is one of the most important technologies of the green communication. Due to the intermittency of the renewable energy and the different space of the Base stations (BSs), the renewable energy cooperation is necessary to improve the renewable energy efficiency...
This paper investigates the problem of robust stability for a class of linear uncertain system with interval time-varying delay. Based on delay-central point method and by means of L-K stability theorem, integral inequality method and convex combination technique, a new delay-dependent stability criterion for the system is formulated in terms of linear matrix inequalities (LMIs). Unlike existing methods,...
In the wireless sensor networks with multiple mobile sinks, the movement of sinks or failure of sensor nodes may leads to the breakage of existing routes. In order to repair broken path with lower communication overhead in terms of both energy and delay, we propose an efficient routing recovery protocol with endocrine cooperative particle swarm optimization algorithm to establish and optimize the...
Currently, service characteristic is rarely considered in service processing for the optical network. In this paper, we introduce a novel service-basedscheme which will buffer and schedule services to optimize the blocking performance of flexi-grid optical network based on Software Defined Network (SDN). This scheme gives sufficient consideration to the diversity of services in SDN network. Besides,...
This paper presents the routing recovery problem of mobile sink wireless sensor networks (mWSNs), which is caused by the sink mobility. We propose an immune orthogonal learning particle swarm optimization algorithm (IOLPSOA) based routing recovery method to build and optimize the alternative path, in order to repair the broken path and maintain the available route from the source nodes to the mobile...
GNSS receivers are vulnerable to replay attacks. Main of previous works suppose all visible GNSS satellites' signals are manipulated by repeaters, which launch replay attacks, and a victim GNSS receiver processes spoofing signals but not legitimate signals. However, in navigation confrontation environment, the supposing is quite difficult to meet. To this end, here a more practicable scenario called...
Three models of a hybrid magnetic suspension system are separately built under the condition of no time-delay, time-delay of the signal of suspension gap and time-delay of arithmetic. To research on the influence of time-delay on the performance of the hybrid magnetic suspension system, relationship between the latent roots of the closed-loop system and time-delay, and the relationship between the...
