ABSTRACT Providing efficient and reliable communication in wireless sensor networks is a challenging problem. To recover from corrupted packets, previous approaches have tried to use retransmissions and FEC mechanisms. The energy efficiency of these mechanisms, however, is very sensitive to unreliable links. In this paper, we present cluster-based forwarding, where each node forms a cluster such that any node in the next-hop's cluster can take forwarding responsibility. This architecture, designed specifically for wireless sensor networks, achieves better energy-efficiency by reducing retransmissions. Cluster-based forwarding is not a routing protocol. Rather, it is designed as an extension layer that can augment existing routing protocols. Using simulations, we demonstrate that cluster-based forwarding is effective in improving both end-to-end energy efficiency and latency of current routing protocols.

    ABSTRACT: Wireless Sensor Networks (WSNs) has very foremost role with all sensing applications, and also have a wide range of easily deployable applications under any circumstances. That's why it is gaining more attention of researchers every day. WSN is resource constraint type of network, without having battery recharging facility. Routing or path finding for data transfer is the main energy consuming operation of sensor networks, a good number of routing and Mac-Layer protocols has been already designed to enhance its energy efficiency. We try to propose a new Position Responsive Routing Protocol (PRRP) by using Global Positioning Systems (GPS) approach for enhancing energy efficiency of wireless sensor network, under certain controlled conditions. Our research discusses various existing WSN routing protocols and propose a new routing protocol with Position Responsive (PR) approach. Research results shows a 23% to 25% significant improvement in overall efficiency of WSN.

    ABSTRACT: The inherent broadcast nature of wireless signals, is responsible for causing interference in various data transmissions. But, when this nature is exploited, the neighboring stations can overhear the data transmissions destined for a particular node. When these neighboring stations help the transmissions by taking a high data rate path instead of the low data rate path, then such a scheme is called a co-operative transmission scheme. The co-operative scheme always promises a higher throughput and lower delay performances. This paper throws a light on the various medium access control (MAC) cooperative protocols developed and at the end, a rigorous comparative study of the features is performed to give a better understanding.

    ABSTRACT: Reliable flooding in wireless sensor networks (WSNs) is desirable for a broad range of applications and network operations, and has been extensively investigated. However, relatively little work has been done for reliable flooding in lowduty-cycle WSNs with unreliable wireless links. It is a challenging problem to efficiently ensure 100% flooding coverage considering the combined effects of low-duty-cycle operation and unreliable wireless transmission. In this work, we propose a novel dynamic switching-based reliable flooding (DSRF) framework, which is designed as an enhancement layer to provide efficient and reliable delivery for a variety of existing flooding tree structures in lowduty-cycle WSNs. The key novelty of DSRF lies in the dynamic switching decision making when encountering a transmission failure, where a flooding tree structure is dynamically adjusted based on the packet reception results for energy saving and delay reduction. DSRF is distinctive from existing works in that it explores both poor links and good links on demand. Through comprehensive performance comparisons, we demonstrate that, compared with the flooding protocol without DSRF enhancement, DSRF effectively reduces the flooding delay and the total number of packet transmission by 12% 25% and 10% 15%, respectively. Remarkably, the achieved performance is close to the theoretical lower bound.
