There are unlimited potentials have been seen in the fields of condition health monitoring, wearable consumer electronics and human motion tracking for the design of soft exosuits. Energy storage devices are the key element in all above mentioned fields, which can be of high capacitance, light weighted and flexible too. Fiber based supercapacitors are based fit to these. In last few decades’ different kind of fiber based supercapacitors have been developed, among them carbon nano-tube (CNT) based fiber electrodes showed that their capacitance, energy density and cycle life is higher as compared to conventional wire based electrodes. In this paper our aim is to review the advances made in the field of different type of fiber basedsupercapacitors.

In the present scenario, wireless network is being widely used in the area where infrastructure based telecommunication system are unavailable. The mobile adhoc network is the infrastructure-less mobile network which has no fixed infrastructure and the nodes can be connected dynamically in an arbitrary manner. The sensor networks are incarnated from ad-hoc networks in which nodes have sensing capability. There are several communication protocols available for wireless sensor networks such as Ad hoc On demand Distance Vector (AODV), Dynamic Source Routing (DSR), Dynamic Destination Sequenced Distance Vector (DSDV). AODV is an on demand dynamic routing protocol that uses sequence number to determine the timeliness of each packet and to prevent loops. The main advantage of this protocol is to establish routes on demand and destination sequence numbers are available for finding the latest route to the destination. However, nodes in sensor networks are usually powered by batteries, which provide a limited amount of energy since sensor nodes have limited battery power. Hence it is required to develop energy efficient routing protocols to optimize the performance of the network. In this paper, Energy Aware AODV (EAODV) routing protocol for IEEE 802.15.4 enabled WSN is developed to improve the performance of the network. The energy aware AODV protocol for IEEE 802.15.4 enabled WSN is done by incorporating the residual energy in the RREQ message of the existing AODV protocol. Further, the performance metrics such as delivery ratio and delay are determined and analyzed for various simulation times and coverage area.
