Priority and Random Selection for Dynamic Window Secured Implicit Geographic Routing in Wireless Sensor Network

Abstract

Problem statement: Sensor nodes are easily exposed to many attacks since it were deployed in unattended adversarial environment with no global addressing and used for critical applications such as battlefield surveillance and emergency response. While the sensor also needs to act as a router to relay a message to a required recipient, then this increased the vulnerabilities to a network layer. However, existing security mechanisms are not permissible to be fitted directly into any sensor network due to constraints on energy and computational capabilities of sensor node itself that require on the modification on the protocols that associated with the sensor node itself in order to provide the security. Approach: In this study, a Dynamic Window Secured Implicit Geographic Forwarding (DWIGF) routing protocol was presented which based on an approach of lazy binding technique and dynamic time on collection window and inherits a geographical routing techniques. Results: The DWIGF was intelligent to minimize a Clear To Send (CTS) rushing attack and robust against black hole and selective forwarding attacks with high packet delivery ratios because of selection of a failed node and an attacker was minimized respectively. Moreover, few routing attacks were eliminated since the routing technique used was classified as geographic routing. Conclusion: This novel routing protocol was promising a secured routing without inserting any existing security mechanism inside.

Comparative Study on Energy Consumption in Dynamic Window Secured Implicit Geographic Forwarding Routing Protocol

“…DWSIGF provided a variable time between 0 to 5 ms. This made the protocol spontaneous and attacker cannot determine the duration of the CTS timer, thus making it less susceptible to attack and even better than SIGF in the case of CTS rushing attack (Hanapi et al, 2009). However its behavior is non-predictable and in some instances the time might not be enough to favor replies to ORTS signal which subsequently result in retransmission.…”

“…Neighbors within the broadcast range (60° sextant) considered eligible to forward the message. On receiving the signal, A CTS response timer is initiated which on expiry, a CTS packet is sent and the data is transferred from the ORTS sender in a DATA message after which an ACK signal is sent to acknowledge the received data (Hanapi et al, 2009;Wood et al, 2006). This same sequence of operation is performed by DWSIGF communication process.…”

“…IGF is a combined routing/MAC protocol that assumes nodes have knowledge of their location (and optionally remaining energy) to make non deterministic forwarding decisions when routing pointto-point traffic (Blum et al, 2003;Hanapi et al, 2009). It uses the concept of lazy binding to establish the stateless property.…”

“…This Node failure can happen due to zero power energy posses by the node and due to security attacks posed on the node and the network (Hanapi et al, 2009).…”
