چکیده

Virtual Backbones (VBs) are expected to bring substantial benefits to routing in Wireless Sensor Networks (WSNs). Connected Dominating Sets (CDSs) based VBs are competitive approaches among the existing methods used to establish VBs in WSNs. Most existing works focus on constructing Minimum-sized CDSs (MCDSs). However, few works consider the load-balance factor. In this work, the size and the load-balance factor are both taken into account when constructing VBs in WSNs. Specifically, three problems are investigated in the paper, namely, the MinMax Degree Maximal Independent Set (MDMIS) problem, the Load-Balanced Virtual Backbone (LBVB) problem, and the MinMax Valid-Degree non Backbone node Allocation (MVBA) problem. We claim that MDMIS and LBVB are NP-Complete and MVBA is NP-Hard. Moveover, approximation algorithms and comprehensive theoretical analysis of the approximation factors are presented in the paper.

Greedy construction of load-balanced virtual backbones in wireless sensor networks

Inspired by the backbone concept in wired networks, a virtual backbone is expected to bring substantial benefits to routing in wireless sensor networks (WSNs). A connected dominating set (CDS) is used as a virtual backbone for efficient routing and broadcasting in WSNs. Most existing works focus on constructing a minimum CDS, a k-connect m-dominating CDS, a minimum routing cost CDS, or a bounde...

Quasi Random Deployment Strategy for Reliable Communication Backbones in Wireless Sensor Networks

Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertak...

K-Connection Maintenance Algorithm for Balanced Routing In Mobile Ad Hoc Networks

In this paper we propose a connection balanced routing in mobile ad-hoc networks (MANETs) using backbone update messages. Virtual-Backbone (VB) construction is very familiar, to overcome broadcast storm problem in wireless networks. In real time, during the movement of nodes in MANET, more number of nodes added in a particular node (say a VB node), it leads poor quality of service in multi-hop ...

Load-balanced CDS construction in wireless sensor networks via genetic algorithm

A Connected Dominating Set (CDS) is used as a virtual backbone for Wireless Sensor Networks (WSNs). Most existing works focus on a Minimum CDS (MCDS), a k-connect mdominating CDS, a minimum routing cost CDS or a bounded-diameter CDS, ignoring the loadbalance factor of CDSs. In this paper, we propose a novel problem – the Load-Balanced CDS (LBCDS) problem, in which constructing an LBCDS and load...

Target Tracking Based on Virtual Grid in Wireless Sensor Networks

One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...
