Abstract
Underwater wireless sensor networks (UWSNs) are used for monitoring costal area and military surveillance applications, for example tsunami prevention and target tracking etc. Jamming is considered to be a serious problem in UWSNs where the intruder affects the lifetime of sensor motes and impact th
Highlights
Wireless communication in underwater scenarios is very challenging such as extreme attenuation makes communication possible only with short-range broadband channels using microwave bands [1], [11]
The underwater wireless sensor network (UWSN) motes that does not carry out any sensing operation on particular slot time are selected as hop motes for other UWSN mote for carryout transmission in optimal and cooperative manner
Cooperative cross layer design keeping contention window size higher aided in utilizing resource more efficiently
Summary
Wireless communication in underwater scenarios is very challenging such as extreme attenuation makes communication possible only with short-range broadband channels using microwave bands [1], [11]. It is affected because of narrow band, multipath fading, reflection, and propagation delay etc Despite such complicated condition of propagation scenarios, underwater wireless sensor network (UWSN) is used by different industries, and military applications. In [18] developed a spatial reuse mechanism considering mitigating near far node effects [20], [21], [22], but ignored proper scheduling as well as delay in transmission, there is a higher probability of packet collision These models are designed considering presence of single jammer scenarios. This paper present efficient resource allocation (ERA) for mitigating multi-jammer adopting cross layer architecture in UWSN. Last section the work is concluded and future improvement of work are discussed
