Özet:

 

The unique features of wireless sensor networks (WSNs) make  them suitable for a wide range of applications in many different  areas.  However, with many of the protocols and algorithms used in  traditional wireless networks, it is usually neither feasible nor  possible to apply them directly to WSNs due to the strict resource  constraints of tiny sensor nodes.  Moreover, application-specific  approaches for communication protocols are usually imposed since WSN  applications have distinct requirements.  In this study, event-driven  WSN applications, where a number of sensor nodes are randomly and  densely deployed in remote and difficult to reach locations, are  targeted.  In such applications, energy efficiency and latency are  crucial design parameters since replacing or recharging the batteries  of sensor nodes is extremely difficult, and any sensed data should be  transmitted eventually.  Considering this aspect, conventional time  division multiple access-based medium access control (MAC) protocols  are not well suited, although there are a few MAC protocols  specifically designed for event-driven WSNs.  In this paper, we  introduce a MAC protocol, named modified bit-map--assisted (M-BMA),  for event-driven WSN applications, designed by employing a new active  node determination method (ANDM) and dynamic time slot allocation  approach.  Utilizing the proposed ANDM, we present that the M-BMA well  supersedes its classical counterpart, offering up to approximately  49% better energy usage as well as up to about 68% fewer message  delays.
