“…Nonetheless, the majority of this work is proposed to repair connectivity problems after their occurrence either by using node redundancy (Wang et al, 2009;Tarng et al, 2009) or node mobility (Erman et al, 2008;Kulkarni and Ozturk, 2011;Tamboli and Younis, 2010). Node redundancy (Wang et al, 2009) is used to overcome disconnected networks.…”

“…Specifically, the cooperating helper nodes can relay the overheard signal from the source by various schemes, such as amplify-and-forward (AF) and decode-and-forward (DF). A variety of cooperative communication techniques were studied for wireless sensor networks [3], wireless local area networks [4], and wireless ad hoc networks [5].…”

In many studies on wireless cooperative diversity, it is often assumed that the number of helpers and their locations are deterministic or known a priori. In this paper, we relax such assumptions and investigate a wireless diversity system with distributed cooperation and spatially random helpers subject to random direction (RD) mobility. To enable opportunistic relaying with multiple helpers, we consider an ALOHA-like medium access control (MAC) scheme and a timer-based random backoff scheme for multi-helper coordination. Particularly, we analyze the upper bound of combined signal-to-noise ratio (SNR) and unconditional success probability with multi-helper cooperation. We also provide numerical approximations for the delay of the two MAC schemes. To characterize the tradeoff between the success probability and delay, we further define a success/delay ratio, which can be maximized by adapting the intensity of selected helpers. The numerical and simulation results validated the analysis accuracy and demonstrated insightful observations.

“…However, the unbalanced energy consumption of the CHs may lead some of the CHs to quickly die and reduces network lifetime of the WSN significantly. Therefore, many researchers have proposed to deploy some special nodes (along with normal sensor nodes) called relay nodes are provisioned with extra energy and higher communication range [2,8,11]. These special nodes act as CHs in the cluster based WSN and are responsible for data aggregation and routing data to the base station.…”

In a two-tier wireless sensor network (WSN), the relay nodes act as the cluster heads for data aggregation and dissemination to the base station. It is very crucial and difficult to find the proper position where the relay nodes can be placed so that the WSN is fully covered and connected. In this paper, we propose an algorithm for placing minimum number of relay nodes with full coverage and connectivity of the WSN with the constraint of minimizing the overall communication cost. The algorithm is based on spiral sequence generated for arbitrarily deployed sensor nodes. The simulation results demonstrate the effectiveness of the algorithm.
