Fault Activity Aware Service Delivery in Wireless Sensor Networks for Smart Cities

Algorithm 2

FA-UOFC algorithm.

,

() Update source rate: Each source node calculates the

source rate for the next period according to

Eq. (28);

() Update resource prices: Using the information of

aggregated transmission rate, link computes a new sole

contention price according to Eq. (25) and

node computes a new energy price according to

Eq. (26);

() Deliver information towards the sink: Sensor node

adapts the contention price and the energy

price along the path, and propagates towards the

sink;

() Feedback message from the sink: The sink feedbacks

the FA parameter and the aggregated resource price to

the source via the reverse path.
