Another issue to consider is; how often BS should change its position?To minimize BS movement once the intensity of messages is neither changing rapidly nor area of these changes migrating too far, what would the threshold (or any other factor) that has influence on decision that BS won't be moved.Since it is the common knowledge that migrating BS could help extend WSN lifespan, it is just a question; how this migration should be organized.There are several aspects to be investigated, among others: whether BS should change its position every time a message is received or not (if not how often should it be?), how far BS should move from its previous (original position), how the BS movement affects behavior of all nodes and the BS neighborhood.Another crucial aspect is how to notify the nodes from BS neighborhood that will soon become out of communication range with BS, when it is moving away from these nodes.
