Wireless sensor network is extensively used technology now a day in real time application. It consists of a number of autonomous sensor nodes which are organized in various areas of interest to accumulate data and jointly convey that data back to a base station. But the sensor node has limited battery energy and it is also found that the WSN more vulnerable to severe kinds of security threats such as denial of service (DOS), Sybil, hello flood attack etc. In this, we proposed group communication using election algorithm to make the network most energy efficient and also make the network secure. The simulation of the proposed methodology is done between different network parameter such as PDR, end-to-end delay, throughput and energy consumption using the network simulator NS-2.34.

“…Similar to the assumption made in [7][8] to describe an e2e error rate, we assume the e2e connection is not in outage, i.e., a packet from the source is received correctly at the destination, only when each hop is not in outage. In other words, the packet is correctly received at each relaying node.…”

In this paper, we present a near-optimum resource allocation strategy for distributed multiple-input-multiple-output multiple hops multiple commodities OFDMA wireless networks. The novel per-hop-optimization strategy aims to reduce the total transmission power of the network while meeting the individual end-to-end outage probability constraint of each commodity, i.e. for each link of the network. It utilizes the Greedy edge-coloring algorithm to determine reused orthogonal subbands for overlapping hops and allows a distributed implementation per hop. In comparison to other bandwidth allocation strategies like equal or dynamic bandwidth for each commodity, our Per-Hop-Bandwidth-Allocation (PHBA) approach uses the bandwidth in a near-optimum way and reduces the total transmission power significantly.

“…For the concept of distributed MIMO adjacent nodes are combined into virtual antenna arrays (VAAs), so that transmission techniques known from multiple antenna systems can be applied [1]- [4]. In each hop the nodes of the transmit VAA serve as virtual antennas of a distributed space-time code and the nodes of the receiving VAA perform independent data detection.…”

Abstract-The throughput of multi-hop communication systems can significantly be increased by the application of MIMO concepts. To utilize the physical resources in an efficient way while meeting the Quality-of-Service (QoS) constraints appropriate power allocation strategies are desired. In this paper the total transmit power of a MIMO multi-hop system is minimized under the constraint of a given end-to-end outage probability. The optimum power allocation corresponds to a convex optimization problem. In order to achieve an analytical solution, the original task is relaxed by stringent approximations and a simple closedform near-optimum solution is proposed. As this Improved Approximative Power Allocation (IAPA) achieves excellent performance results this new approach is also very useful for investigating outage restricted multi-hop systems analytically.
