Using mobile sensor networks has increased as well in recent years. It is because of the movement ability of sensor nodes which can be very useful in such networks. Having failure for network nodes occurs usually in wireless sensor networks which can be avoided by having the ability of movement in sensor nodes. It means that when a node fails consequently a hole appears in the coverage area of ...

purpose: reconstruction programs have two approaches: in-situ reconstructions and relocation. different experiences around the world show little acceptance of relocation programs by people which new sites were left or did not return to their pre-boom. meanwhile, estalkhkooh village relocation program shows vice versa. villagers not only accept their new relocated village but also are trying to ...

Sink relocation is essential in wireless sensor network since relocating sink can balance the traffic load in the midst of multiple nodes and thereby decrease the miss rate of real-time packets. The main constraint in wireless sensor networks is limited energy supply at the sensor nodes so it is important to deploy the sink at a position with respect to the area of interest; a specific area tha...

Although in most of the rural development plans, relocation of informal settlements is oftenconsidered as an efficient solution to increase safety of rural communities against natural and man-made disasters,such as, earthquakes, fire hazards, floods, etc. an evaluation of recent experiences in the relocation projects show thatthe relocated community is often unsatisfied with the new residential...

Wireless Sensor Networks have gained attention of researchers because of its wide area applications like search and rescue operation and battlefield reconnaissance. WSN consist sensor nodes which monitor the environmental conditions such as temperature, humidity. These Sensor nodes are inherently prone to failure due to constrained resources and there deployment in harsh environment. Nodes get ...

Mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. Nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. A failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. A number of approaches have bee...

Wireless sensor networks (WSNs) have gained worldwide attention in recent years. These are of great significance in resolving many real-world problems, and have attracted increasing research interests in recent years. In this paper, we consider a hybrid sensor network with fifty sensor nodes, where a subset of the nodes has movement capability, possibly at high energy expense. A static sensor n...

Mobile sensor nodes such as hopping sensors are of critical importance in data collection. However, the occurrence sensing holes is unavoidable due to energy limitation nodes. Thus, it evident that relocation mobile most desirable method recover holes. The previous research conducted by authors so far demonstrated realistic scheme, which suitable for distributed environment. In studies, cluster...

In parallel computer systems with a number of processors, external fragmentation is caused by continuous allocation and deallocation of processors to tasks which require exclusive use of several contiguous processors. With this condition, the system may not be able to find contiguous processors to be allocated to an incoming task even with a sufficient number of free processors. Relocation is a...

Primary adenocarcinoma is a rare and late complication following proctocolectomy and ileostomy for ulcerative colitis, familial adenomatous polyposis, Crohn's disease and multifocal colorectal cancer. We report a case of adenocarcinoma of the ileostomy occurring 48 years after proctocolectomy for ulcerative colitis. A review of the literature suggests that there are 39 cases reported in literat...
