Mobile Ad-hoc Network (MANET) is defined as a combination of mobile nodes that lack a fixed infrastructure and is quickly deployable under any circumstances. These nodes have self-aware architecture and are able to move in multiple directions, which renders it dynamic topology. Its dynamicity makes routing in MANET rather challenging compared to fixed wired networks. This paper aims to perform a comparative study on the three categories of MANET routing protocol by comparing their characteristics and operations, as well as their strength and weaknesses.

Many objects around us are placed on a network via wireless sensor network (WSN). This type of network is considered new technology and it begins to grow and raised in order to allow data to be stored, processed and accessed in an efficient way. It is used for observing, checking, or keeping a continuous recording of a process or quantity of ecological circumstances such as heat range, audio, pressure and wetness to hand in glove successfully go their data over the network to specific location . The difficulty in WSN network is that the network access is not secure or not safe when data transmits through wireless environment. It is susceptible to assault and intruders. Additionally, denial of services attacks much more damaging. Security issues are biggest issue in the field of wireless sensor networks. This paper focuses on looking at the current safety troubles of wireless sensor networks and recommended suitable controls to triumph over these problems.
