Fault-tolerant and QoS based Network Layer for Security Management
Abstract: Wireless sensor
networks have profound effects on many application fields like security
management which need an immediate, fast and energy efficient route. In this
paper, we define a fault-tolerant and QoS based network layer for security
management of chemical products warehouse which can be classified as real-time
and mission critical application. This application generate routine data
packets and alert packets caused by unusual events which need a high
reliability, short end to end delay and low packet loss rate constraints. After
each node compute his hop count and build his neighbors table in the
initialization phase, packets can be routed to the sink. We use FELGossiping
protocol for routine data packets and node-disjoint multipath routing protocol for
alert packets. Furthermore, we utilize the information gathering phase of
FELGossiping to update the neighbors table and detect the failed nodes, and we
adapt the network topology changes by rerun the initialization phase when
chemical units were added or removed from the warehouse. Analysis shows that
the network layer is energy efficient and can meet the QoS constraints of
unusual events packets.
