    Wireless sensor network: Routing protocols and attacks - A survey
    (Institute of Electrical and Electronics Engineers Inc., 2015) Purohit, R.; Sidhu, N.
    Based on end user application a network of hundreds or even thousands of sensor nodes, also known as wireless sensor network, can collect valuable data from an unassisted environment and transmit the information to the user. This transmission can be routed from one node to another using numerous routing protocols for wireless sensor network. Though purposive, there are some constraints of the sensor nodes due to computing power, storage capacity and limited power. In this review article, we will discuss wireless sensor network's architecture. Further, we will discuss classification of routing protocols according to some factors and summaries on their mode of operation. Lastly, we put up a comparative study on these protocols. ? 2015 IEEE.

    Analysis of MAODV MANET routing protocol on different mobility models
    (Institute of Electrical and Electronics Engineers Inc., 2018) Kaur, N.
    MANET is an infrastructure less network. It has various applications in fields like military, commercial sector, local level, etc. MANET is easy to setup, configure and build. Due to infrastructure less network, MANET relies on the cooperation of nodes for communication. In MANET, communication between the nodes is possible with the help of protocols which are categorized into three types like reactive, proactive and hybrid. In the reactive category of protocol, a path is established at the real time. In the proactive category, protocols have predefined routing tables for each node. The hybrid category is the combination of both these categories. Modified Ad-hoc On-Demand Distance Vector (MAODV) is the reactive protocol which defines all possible routes among source node and the destination node which are maintained during data transmission. In the case of a disappointment of definite route, the data packets are transferred through secondary routes which were established with the help of routing tables that stores the multiple route paths to the destination. In the real world, nodes in MANET are allowed to transfer in any direction. Thus movement models like Random Way Point (RWP), Random Walk (RW), Random Direction (RD) and Gauss-Markov (GM) are taken as they have different mobility patterns. Therefore, M-AODV is implemented over different mobility models to compute parameters like End to End Delay (E2E Delay), Average Hop Count (AHC), and Throughput. ? 2017 IEEE.
