An integrated framework for Performance enhancement in Hierarchical cluster based Wireless sensor network

Abstract

Wireless Sensor Networks WSN have been recognized as a newlinerevolutionary technology for interrogating the physical world and committed newlinein a wide variety of applications in the present scenario They make a newlinesignificant contribution to the emerging fields like ambient intelligence newlineubiquitous and pervasive computing WSNs differ from traditional wireless newlinenetworks and are typically self organizing with a potentially huge number of newlinerandomly deployed battery driven sensor nodes The nodes cooperatively newlinecommunicate with each other to accomplish a common task and the design newlinemust enforce stringent constraints in terms of energy cost and reliability newlineOperating WSN nodes in resource constrained environment either newlineby changing or recharging batteries is an unmanageable task and the failure newlineof single node due to low energy can affect the entire system It is imperative newlineto develop an energy efficient protocols focusing at node and network level newlineThe WSN applications which involve both real time non realtime newlineData allocation of priority and proper scheduling among the data newlinepackets are of vital importance to reduce sensor energy consumption and endto newlineend data transmission delays newline newline
