Abstract
This paper presents the performance analysis of our proposed energydelay
aware coordination protocol, ADP [1] (Actuator Discovery Protocol)
for mobile SANETs (Sensor and Actuator Networks). We have presented
our analysis on ADP for static SANETs in an earlier work and it is shown
that ADP provides optimal attachment for a sensor node to the actuator with
minimum cost. For the sensor-actuator coordination, the proposed ADP can
guarantee ordering, synchronization and eliminates the redundancy of actions
[1]. In this work, we present our analysis on the dynamics of ADP
to handle mobile sensor and actuator applications. The interval chosen to
validate the acquired paths through ADP due to mobility can be a direct
mapping of application’s energy and delay constraints. Our NS-simulations
show that the total-energy consumed to validate the paths for time-stringent
traffic is actually less compared to the overall energy consumed during arbitrary
transmission of sensor data to-wards the sink. We have utilized a
random way-point mobility model in our ns-simulations and analyze the performance
of ADP in terms of energy estimates for maintaining paths (toward
the optimal-actuator) in order to keep a promised QoS for time-stringent applications.
The proposed ADP has also achieved a good balance for sensor
energy-consumption while keeping a low end-to-end delay (optimal number
of ’message-exchange’ to keep the paths updated).
Keywords: SANETs (Sensor and Actuator Networks), self-organization,
coordination protocols, energy and delay aware coordination protocols.
