MANEMO for Fishing Trolleys in Deep Sea

The present work considers a fleet of fishing trolleys. The MANEMO is the integration of mobile ad-hoc network technology and mobile network technology for maintaining the uninterrupted connectivity among the fishing trolleys in deep sea. It provides local connectivity among the fishing trolleys for offshore help using mobile ad-hoc network and global connectivity among the fishing trolleys for onshore help using mobile network. Each fishing trolley works as a separate node in case of local communication whereas all the fishing trolleys form a mobile network in case of global communication. The routing algorithm in MANET environment selects an optimal route for a session before starting transmission of data packets associated with that session. It uses route maintenance algorithm to detect whether a trolley associated with an existing route is going out of the communication range during the ongoing session in advance before the existing route fails completely. Such consideration helps to reduce the data packet loss. If the local communication among trolleys fails due to the change in network topology the rest of the communication can be maintained globally which helps to provide the uninterrupted connectivity to the fishermen in the deep sea. The performance of the proposed scheme is evaluated on the basis of initial path set up time and average packet delay.
