Due to these obstacles disconnection between sensor nodes?? How to prolong network life time in wsn??
SOME OF THE OBSTACLES IN WIRELESS SENSOR NETWORKS
(1) Inaccurate algorithm design
(2) Overcoming tamper-resistant hardware and mirroring signal
(3) Corruptibility of memory contents on the sensor chip also power fluctuation results to inaccurate data/information

Hello Amar,
One of the founding article about obstacles is due to Amit Jardosh and his colleagues: --> Amit Jardosh, Elizabeth M. Belding-Royer, Kevin C. Almeroth, and Subhash Suri. "Towards Realistic Mobility Models for Mobile Ad hoc Networks." In the Proceedings of MOBICOM, San Diego, CA, September 2003.
You can find his paper directly on its web page: http://moment.cs.ucsb.edu/~amitj/

Hope this helps.

For prolonging WSN lifetime due to energy consumption, you may refer to my recent paper:
Article PCAC: Power-and Connectivity-Aware Clustering for Wireless S...
For increasing the network life time there are many papers available in the net. You cal also have a look at this paper co authored by me "Self Organized, Flexible, Latency and Energy Efficient Protocol for Wireless Sensor Networks" in Springer publications .... and also our publication mentioned below available in Researchgate.
Hope it helps. All the best for the Research.
Conference Paper FAMACRO: Fuzzy and Ant Colony Optimization based MAC/Routing...
The network life time in WSN can be increased by the energy consumption reduction/ optimization by the use of energy efficient network protocols.
Frequent node and channel failures continue to degrade performance and availability in WSNs.
