    Geographical location based hierarchical routing strategy for wireless sensor networks
    (2012) Kumar, P.; Chaturvedi, A.; Kulkarni, M.
    The overall performance and thus the achievable efficiency of wireless sensor networks (WSNs) rely on the type of protocols deployed to support particular application in hand. In WSN, network's lifetime depends upon the residual energy of individual nodes. In this paper; a brief survey comprises of various reported methodologies that make uses of geographical location attributes for routing in WSN is presented. To assist the routing algorithm on location aspect of the source and destination as well as other intermediate nodes; a location index is formulated based on binary encoded spatial frames. The merit of proposed spatial encoding scheme is its supportiveness on scalability aspects, so it can be easily tailored to accommodate hierarchy based network architectures. Further, the scheme incorporates an effective mechanism to select cluster heads for each cluster in such a way so as to avoid the localization of hot spot effects right from cluster level to network level. © 2012 IEEE.

    Efficient path finding algorithm for transmission of data in agricultural field using wireless sensor network
    (Springer Verlag service@springer.de, 2013) Pai, S.N.; Shet, K.C.; Mruthyunjaya, H.S.
    Transmission of data from the source to the sink requires an efficient path so that the network life is enhanced. Longer shelf life for battery is essential when it is difficult to replace the battery too often as in agricultural field. To achieve this, in this paper we have proposed an algorithm to find the efficient path between the sink (base station) and the source so that the network can be alive for one cropping season. © 2013 Springer-Verlag.

    A survey and comparison of GTS allocation and scheduling algorithms in IEEE 802.15.4 wireless sensor networks
    (2013) Rao, S.; Keshri, S.; Gangwar, D.; Sundar, P.; Geetha, V.
    Multimedia applications in the wireless domain require not only contention-based communication, but also reservation based one. The IEEE 802.15.4 standard is widely used for Wireless Sensor Networks (WSNs), and is a standard for low rate, low power and low cost WPANs (Wireless Personal Area Networks). Moreover, it supports the allocation of Guaranteed Time Slot (GTS) to the devices in Contention free period (CFP). With time, many GTS scheduling and allocation algorithms have been proposed with the aim to make maximum the use of GTS. This paper provides a survey and comparison on the current state-of-the-art researches in this important area. We have firstly summarized all the important algorithms proposed till now and then classified and compared them based on various parameters including type, delay, bandwidth, cost, topology, traffic and energy efficiency. © 2013 IEEE.

    Distributed data aggregation in wireless sensor network: With peer verification
    (SciTePress, 2016) Chatterjee, S.; Pais, A.R.; Saurabh, S.
    Data aggregation in wireless sensor network is implemented to reduce the communication overhead and to reduce bandwidth utilization. Data confidentiality requires the sensor node to transmit the data in a secure manner so that the adversary is unable to read the data or transmit false data even if it compromises some of the sensor nodes or aggregation node. In this paper a distributed aggregation protocol using homomorphic trapdoor permutation is proposed. This protocol distributes the responsibility of key generation, aggregation and verification to different nodes to reduce the overall power consumption of the sensor network. The peer verification scheme is also proposed as a part of the protocol. Peer verification ensures the authentication of the data and sender node in the network, by at least k peer nodes. Security of the proposed protocol is analyzed against passive and active adversary model. © © 2016 by SCITEPRESS - Science and Technology Publications, Lda. All rights reserved.

    The use of Multi-point Crossover Genetic Algorithm for Clustering the Nodes in WSN
    (Institute of Electrical and Electronics Engineers Inc., 2018) Batta, K.B.; Rao, G.V.; Murthy, Y.V.S.
    In this work, an effort has been done on two important objectives of wireless sensor networks (WSNs) such as optimization of the energy consumption and lifetime. Since these two objectives have lot of impact on producing quality services in wireless networks, these two are considered and the solution is identified through clustering based models. Cluster information is maintained with the as it is appropriate solution for both the objectives. Also, experimentation is done using multi-point crossover genetic algorithm (GA) approach to optimize the time to transmit the information as well as to improvise the life time of a sensor node. Improvised efficiency is found with this effort and the results are compared with existing LEACH and GA using single point crossover techniques. Copy Right © INDIACom-2018.

    An energy-efficient static multi-hop (ESM) routing protocol for wireless sensor network in agriculture
    (Institute of Electrical and Electronics Engineers Inc., 2018) Dubey, A.K.; Upadhyay, D.; Santhi Thilagam, P.S.
    Energy efficient routing is a crucial area of research for wireless sensor network(WSN). The communication between the wireless sensor nodes is handled by the routing protocols. The nature of the link, low power and limited recourse makes it a difficult task to design an energy and performance efficient routing protocol for WSN. This paper proposes an energy-efficient route selection protocol for a multi-hop network with a static link for deployment in the field of agriculture. An energy model is also given in this paper to evaluate the energy consumption of the network. The proposed energy-efficient static multi-hop(ESM) routing protocol is evaluated based on the performance parameters for energy efficiency, network lifetime and pack loss and compared with an existing scheme. The simulation results represent that the proposed protocol increases the network throughput and the lifetime. © 2018 IEEE.
