The key challenge a Wireless Sensor Networks (WSN) routing has to deal with is the energy efficiency and prolonging network lifetime. WSN is composed of a set of sensor nodes and a sink node. The role of sensor nodes is to gather data from their surroundings and send out it to the ...
So the clash between packets would take place in this scenario. There is no method to find out these types of the collisions in WSN. Self-interference is also one of the challenges of the sensor network which is occurred in successive hops. The problem of dynamism is in that the links ...
However WSN presents many challenges. These networks are prone to malicious usersattack, because any device within the frequency range can get access to the WSN. There is a need forsecurity mechanisms aware of the sensor challenges (low energy, computational resources, memory,etc.). Thus, this ...
challenges to the design and management of sensor networks. In the existing literature, there are a lot of routing protocols that have been proposed targeting WSNs, such as LEACH (Heinzelman et al., 2000),Directed Diffusion(Intanagonwiwat et al., 2000), TEEN (Manjeshwar and Agrawal, 2001...

One of thekey challenges is how to make full use of the limited energy to prolong the lifetime of the network,because energy is a valuable resource in WSNs. The status of energy consumption should be continuouslymonitored after network deployment. In this paper, we propose coverage and ...
These are the main challenges facing routing in WSNs. 2.1.1 Energy Consumption: The main objective of the routing protocols is efficient delivery of information between sensors and the sink. To this end, energy consumption is the main concern in the development of any routing protocol for WSNs....
The research on routing combined with data aggregation in WSNs has previously uncovered new opportunities and challenges. ^ In this research we develop three routing protocols that incorporate the data aggregation, under the hierarchical routing topology. First, we propose a distributed cluste...
Since a WSN consists of potentially hundreds of low cost, small size and battery powered sensor nodes, it has more potentials than a MANET to be deployed in many emerging areas. However, they also raised many new challenges, and these challenges include the design of embedded sensors and ...
