This paper presents a file transfer global dynamic scheduling algorithm that incorporates the two optimizations of multi-hop path splitting and multi-pathing in conjunction with the use of available file replicas, This algorithm makes use of information from past GridFTP transfers to estimate network bandwidths and resource availability. The experimental results show that this algorithm achieve significant...
In order to maximize the network lifetime for target coverage, we propose a heuristic greedy optimum coverage algorithm (HG-OCA). In HG-OCA, we first design a network model in which power supplies of sensor nodes follow a normal distribution. Next, we analyze energy model of target coverage, educe three rules to reduce network scale, present the concept of the key target and the prior coverage of...
