SGDD: self‐managed grid‐based data dissemination protocol for mobile sink in wireless sensor network

Abstract

SUMMARYThe reduction of energy consumption in order to increase network lifetime is one of the most major challenges in the design of wireless sensor networks. During data dissemination, the sensors that are located in the sink's neighborhood are responsible to relay data to the other nodes; hence, their energy is exhausted expeditiously. Therefore, the idea of utilizing mobile sinks can be so advantageous to decrease energy consumption during data dissemination process. In this paper, we propose self-managed grid-based data disseminating protocol for mobile sink in wireless sensor networks by using the idea of constructing a virtual grid. In self-managed grid-based data disseminating protocol, sink and nodes map their geographical position to a virtual location. In order to increase the performance, we have employed a cell head for each grid cell. Cell heads are selected based on two parameters, centralization and residual energy. Our data dissemination protocol is simple and has low overhead to construct and maintain. Also, we have presented a new method for sink location update, which leads to the least cost in data transfer. Simulation results illustrate that by utilizing hierarchical functionality and determining an optimal size for grid cells, energy consumption is decreased, which leads to increasing network lifetime.

Ant colony optimization algorithm based on mobile sink data collection in industrial wireless sensor networks

“…Besides, λ 1 and λ 2 is equal to 0.5. The proposed method is compared with related works, data-driven routing protocol (DDRP) [31] and self-managed grid-based data dissemination protocol (SGDD) [32], for data aggregation with mobile sink. Figure 1 shows the comparisons of the average delay of data collection in mobile sink mode.…”

“…However, the experimental results clearly show that the average energy consumption of DDRP is much higher than that of the other two algorithms. Next, to verify the effectiveness of the proposed algorithm, its performance is compared with DDRP [31] and SGDD [32] in terms of the average hops, average residual energy, and network life time for different numbers of sensor nodes. Figure 3 illustrates the average number of hops from normal nodes to mobile sink for different numbers of sensor nodes.…”

Mobile Sink Path Formation to Extend the Network Lifetime in WSN

“…Self-managed grid-based data dissemination approach using the MS to equate the network load is discussed in [8].Here, the sensors are associated in to clusters and choose the CHs. Then the CH collects and communicates the observed the data to the BS by the MS.…”

“…CH) that collects data from the members of the grid. Several grid-based data collection schemes with one or multiple mobile sinks have been proposed for handling energy conserving in WSNs [14,15]. However, existing approaches have a heavy grid construction phase in terms of communication overhead and are not scalable when the sink must move to each CH of the grid.…”
