“…After determining the communication parameters and relay nodes, the source node could transmit the data to the sink node. Their energy consumption model was adopted in , where the cooperative MIMO scheme was designed for multi‐hop WSNs, and the cooperative MIMO clustering and routing were jointly considered. The work concentrated on cooperative routing with MISO links in multi‐hop wireless networks.…”

“…Because of the limitation of size and resource, each node is equipped with a single omni‐directional antenna and has finite energy. Our model is based on AWGN channel, and the modulation scheme is Binary Phase Shift Keying (BPSK) . The transmission rate in our system is fixed, so its effect on energy consumption is neglected.…”

“…The transmission rate in our system is fixed, so its effect on energy consumption is neglected. We adopt the main aspects of physical layer in , which is similar to most of other works about vMIMO communication . In fact, our routing schemes also adapt to other physical layers with slight alterations.…”

“…However, there are two main disadvantages in previous works. On the one hand, most routing algorithms build up vMIMO transmission on the fixed structures (e.g., clusters) so as to save the energy consumption for wireless networks. We give an example of the route with clusters in Figure (a), where the gray nodes represent cluster heads.…”

“…Second, the selection of transmission modes is restricted in many works . For example, the work designs a routing method is using the alternate SIMO‐MISO modes, which may reduce the spatial diversity for multi‐hop routing. So, how to find the optimal combination of cooperative modes for wireless routing is a challenge too.…”

Virtual multi-input-multi-output (vMIMO) technology is becoming a promising way to improve the energy efficiency of wireless networks. Previous research always builds up the vMIMO-based routing on the fixed structure such as clusters, and the MIMO mode is omitted in most cases. So, they cannot fully explore the advantage of vMIMO in routing. In this paper, we study a general routing scheme in which no fixed structure is required, and any communication mode of vMIMO is allowed for sake of the energy efficiency. We define two vMIMO-based routing problems aiming to energyminimization and lifetime-optimization. The first problem can be solved by our distributed energy-minimum vMIMObased algorithm. The algorithm constructs the virtual cooperative graph, and applies the shortest path method on the virtual cooperative graph to solve this problem. The second problem is non-deterministic polynomial-time hard, and we design the distributed lifetime-oriented vMIMO-based algorithm, which is based on the modified Bellman-Ford method. It can reach approximation ratio of four. The simulations show that our algorithms can work well in many situations. For example, distributed lifetime-oriented vMIMO-based algorithm can prolong the lifetime about 20.2% in dense topologies compared with the cooperative routing algorithm on average.

In this paper, a robust mobility assisted WSN routing protocol named QoS oriented and Energy Efficient Routing Protocol for Cooperative Multiple Input Multiple Output (MIMO) based mobile WSNs (Q-E2RPC) has been developed that exploits the efficiency of network partitioning, Fuzzy Clustering Mean (FCM) and Expectation Maximization (EM) based clustering, Fuzzy Logic Controller (FLC) based Cluster Head (CH) selection and mobile sink based data gathering to meet QoS demands and energy efficiency. Unlike classical clustering methods FCM and EM as a cumulative solution enables optimal clustering, which is followed by the multiple network parameters based CH selection. The use of single mobile sink avoided multi-hop transmission and signaling overheads that eventually reduced energy consumption. Q-E2RPC protocol exhibited timely data delivery, low energy consumption, and reduced signaling overheads. The results exhibited that Q-E2RPC outperforms other state-of-art techniques in terms of higher throughput, low delay and energy consumption, and higher network efficacy.
