Description: The sensor nodes of a wireless grain depot surveillance system are deployed in crystal grids, which provide lot of valid position information. To avoid the energy consumption unbalance of the single hop routing model adopted by LEACH protocol, a novel hybrid routing model is proposed in this paper. Multi-hop routing is introduced into the distant field nodes through right angle transferring of approximate equivalence consumption path. And the average energy consumption is used as a threshold of selecting intermediate transferring nodes to minimize total variance of node s energy consumption, so that balance the whole network. Simulations show that the hybrid model eliminates hot spots within cluster and prolong the lifetime ofWSN. -The sensor nodes of a wireless grain depot surveillance system are deployed in crystal grids, which provide lot of valid position information.

Description: LEACH [1] is an autonomous adaptive clustering protocol that distributes the energy load evenly among the sensors in the network using randomization. The nodes organize themselves into local clusters, with one node acting as the local base station or cluster head. In order to not drain the battery of a single sensor randomized rotation of the high-energy cluster head position such that it rotates among the various sensors. Once the cluster head has all the data from the nodes in its cluster, the cluster head node aggregates the data and then transmits the compressed data to the base station. Since it compress the amount of data being sent from the clusters to the base station, energy dissipation is reduced and system lifetime is thus enhanced.

Description: Wireless sensor networks with mobile sink are ex-pected to increase the flexibility for gathering information in large-scale sensing and detecting environments. Energy saving becomes one of the most important features of the sensor nodes to extend their lifetime in such networks. A novel tree-based power saving scheme is proposed in this paper to reduce the energy consumption in wireless sensor networks with mobile sink. We adopt a dynamic sorting algorithm to create a tree-cluster routing structure for the sensor nodes. The main goal of this scheme is to reduce the data transmission distances of the sensor nodes by employing the tree structure and multi-hop concepts. Based on the location of mobile sink, the distances between the sensor nodes, and the residual energy of each sensor node, the proposed scheme makes an efficient decision for creating the routing structure. The energy consumption is reduced and the lifetime is extended for the sensor nodes by balancing the network load.

Description: Routing protocols in Wireless Sensor Networks (WSNs) emphasize on data dissemination, limited battery power and bandwidth constraints in order to facilitate efficient working of the network, thereby increasing the lifetime of the network. In this paper, the authors present an Energy Aware Multi-hop Multi-path Hierarchical routing protocol (EAMMH). EAMMH protocol organizes the sensor nodes into clusters and forms a multi-hop intra-cluster network. It establishes multiple paths each sensor node to the cluster head and provides an energy aware heuristic function to choose the optimal path.-Routing protocols in Wireless Sensor Networks (WSNs) emphasize on data dissemination, limited battery power and bandwidth constraints in order to facilitate efficient working of the network, thereby increasing the lifetime of the network.

Description: The reliable data delivery is a challenging task in Wireless Sensor Networks (WSNs) due to dynamic and unpredictable changing behaviors of nodes. The traditional cryptographic and authentication based schemes can’t be adopted due to their associated cost and incapability to counter nodes misbehavior attacks. Recently, trust based solutions have proved to be more effective to address nodes’ misbehavior attacks. Apart isolating misbehaving nodes, the existing trust based schemes lacks the capability to minimize link failure notifications due to transient transmission disruption which consequently give rise to frequent route breakages thereby undermining throughput and route stability. Moreover, the existing solutions give rise to high energy consumption and control overhead in pursuit of trust estimation and network-wide dissemination which not only adds to network congestion but also undermines network lifetime. In this paper, we present a Trust and Energy aware Routing Protocol (TERP) that -The reliable data delivery is a challenging task in Wireless Sensor Networks (WSNs) due to dynamic and unpredictable changing behaviors of nodes.

Description: In a heterogeneous wireless sensor network (WSN), relay nodes (RNs) are adopted to relay data packets from sensor nodes (SNs) to the base station (BS). The deployment of the RNs can have a significant impact on connectivity and lifetime of a WSN system. This paper studies the effects of random deployment strategies.
