Adaptation of LEACH routing protocol to cognitive radio sensor networks

One of the drawbacks of LEACH protocol is the uncontrolled selection of cluster heads which, in some rounds, leads to the concentration of them in a limited area due to the randomness of the selection procedure. LEACH-C is a variant of LEACH that uses a centralized clustering algorithm and forms good clusters through sink control. According to experimental results, the IEEE 802.15.4 packets are damaged by WLAN interferences in ISM band. It seems that, sensor nodes equipped with cognitive radio capabilities can overcome this problem. In cognitive radio sensor networks (CRSN), routing must be accompanied by channel allocation. This requires spectrum management which can be devolved to cluster heads. For this networks, new duty cycle mechanisms must be designed that jointly consider neighbor discovery, and spectrum sensing/allocation. Cluster-based network architecture is a good choice for effective dynamic spectrum management. In such architecture, cluster heads have a proper spatial distribution and are optimally located all over the network. In this paper, using the physical layer information and preserving the feature of random cluster head selection in LEACH, it has been tried to both move the position of cluster heads to appropriate locations and make their quantity optimal. The simulation results show that the transferal of cluster heads to appropriate locations increases the network lifetime significantly though this comes at the price of early instability appearance. By considering the energy level in cluster head election algorithm, one can overcome the network stability issues too. However, this will move the cluster heads away from their appropriate locations. © 2012 IEEE.

Law, governance and risk: deconstructing the public-private divide in climate change adaptation

The article focuses on the public–private divide in law and which organizes principles for and governance. It analyzes the governance model of public–private divide regarding for climate change adaptation in context to a case study of water governance and flood risk. It compares the relationship between state and individual laws which helps in policy setting.

Words, oral libraries and environmental responses : an Australian indigenous perspective to climate change adaptation

Climate change adaptation and mitigation continues to be a prevalent discourse in this country and internationally in both the sciences and the arts. While various types and degrees of change are evident, the quantification of these changes including their scope and diversity have challenged conventional sciences. This is demonstrated in their inability to succinctly answer key questions about change including the degree of change and associated patterns and consequences. Most of this discourse is nested in a temporal band comprising the last 100-200 years of data and evidence, and very much informed by Western science perspectives and protocols. Little attempt has been made to engage with Australian Indigenous communities whom possess environmental knowledge of some 10,000-100,000 years albeit embedded in their artistic and oral narrative 'histories'. This paper explores the role and values that Australian Aboriginals, the Indigenous peoples of the Australian content, can offer in shedding new light on this discourse While focusing upon a cross-peri-urban Indigenous investigation, it examines this discourse though the lens of their words, terms, sentences as a vehicle to better understand a longitudinal perspective about climate change adaptation pertinent to Australia.
