Network Lifetime Enhancement by Elimination of Spatially and Temporally Correlated RFID Surveillance Data in WSNs

Algorithm 1

Proposed algorithm (m-TDBF).

Input: RFID Data

time

Output: is Redundant or not

Step 1: Begin

Create two events

Event (Hash mapping of arrival tid)

Event-check(for comparison)

for no. of IDs(1)

[Hash mapping]

  Step 2: Initiate proposed algorithm

  for K no.of IDs(i)

  if [Already detected that is why ]

  Update TDBF()

  else [detected for the first time]

  if [no need to check time as already checked in RSSI condition above.

  Only check the threshold within the range]

  Update TDBF (x.time, x.RSS)

[x is in range or not decided by RSS and

whether after certain time interval checked by first condition]

Update TDBF (x.time, )

Send to

break

elseifx.timer¿TDBF_P[i] [time]

and

Update TDBF (x.time, x.RSS)

Send x to Event check

break

end if

Identify x by comparing Event and Event check
