On the deployment of wireless data back-haul networks

Abstract: Abstract-We study the deployment of data back-haul nodes for wireless networks with energy constraints. We address the following problem: given the required lifetime of a sensor network, the energy constraint of back-haul nodes, and the area to be covered, what is the minimum number of nodes needed to construct such a back-haul network and what is the corresponding deployment scheme? Finding an efficient deployment scheme involves location management, routing, and power management. We focus on linear networks … Show more

“…The goals of our simulation studies are: (1) to demonstrate the difficulty in obtaining feasible solutions for the K-connected DPAP through a purely random process, (2) to test the strength of the proposed operators at improving the performance of MOEA/D at dealing with the K-connected DPAP and (3) to demonstrate the effectiveness of the proposed DPAP-specific MOEA/D-RH against the popular constrained NSGA-II in several WSN instances, giving the trade-off of the objectives and a variety of feasible network design choices.…”

“…We assume a perfect medium access control, such as SMAC [29], which ensures that there are no collisions at any sensor during data communication and we adopt the simple but relevant path loss communication model as in [2]. In this model, the transmit power level that should be assigned to a sensor i to reach a sensor j is [2,6] is the path loss exponent and b = 1 is the transmission quality parameter. The energy loss due to channel transmission is d a ij , where d ij is the Euclidean distance between sensors i and j.…”

“…Following this idea, some research works, such as Liu and Mohapatra 21 and Guo et al, 22 have addressed the linear sensor deployment problem, where nodes can be placed anywhere along a continuous pipeline. However, nodes can locate segmentally in boxcars for train monitoring to meet the requirements above.…”

“…(3) The set of pre-defined potential positions is denoted by P = {p 1 Therefore, we have to place a relay ζ r on any one of the potential positions from ComSet(τ i ) to ensure connectivity of τ i . (7) W denotes the set of relay nodes, which provides k-connectivity to all targets and ω i denotes the set of relay nodes that those are providing k-connectivity to τ i .…”
