    Survey on routing protocols for Internet of Things
    (Institute of Electrical and Electronics Engineers Inc., 2017) Bhat, A.; Geetha, V.
    As Wireless Sensor Network nodes are ID based network, it would be difficult to monitor the status of the same when it is connected to Internet of Things. So gateway is required to connect the network with Internet. In order to access and manage the network remotely, it is good to have IP based devices connected with each other. As IPv4 is being depleted, IPv6 was a solution for much larger address space. IP connectivity in sensor networks mainly depend on two IETF standards: 6LoWPAN and RPL. Routing protocol in 6LoWPAN is very precise due to limited node's potential. Existing protocol of 6LoWPAN does not satisfy Low power Lossy networks. IETF came up with IPv6 routing protocol for low power Lossy networks called RPL. © 2017 IEEE.

    Hop count, ETX and energy selection-based objective function for image data transmission over 6LoWPAN in Internet of Things
    (Inderscience Publishers, 2024) Bhat, A.; Geetha, V.
    Internet of Things (IoT) is a technology which connects millions of things to the internet for collecting data and controlling things. 6LoWPAN is designed with the idea to connect resource-constrained IoT devices. The current design of 6LoWPAN poses several challenges to support multimedia IoT devices such as cameras and audio recorders. This paper addresses one of the challenges in the area of parent selection with a new hop count, ETX and energy selection-based Objective Function (OF) for multimedia data traffic. The performance of the proposed OF is compared with existing OF with respect to packet delivery ratio, control traffic overhead, energy consumption and latency running simulations on different topologies in Cooja. The results of the simulations indicate the proposed OF performs better than existing methods in all the areas measured. Experimental results mention that the proposed HEE-OF improves PDR, overhead and energy parameters by 4%, 6% and 3%, respectively. © 2024 Inderscience Enterprises Ltd.
